Archery Terms Explained: 2026 Beginner’s Glossary for Compound, Recurve & Arrows
Walking onto an archery range for the first time can feel like entering a conversation in another language.
Draw length.
Arrow spine.
Let-off.
Brace height.
FOC.
Cam timing.
Center shot.
Experienced archers throw these terms around naturally, but for beginners, understanding them can make the difference between simply owning a bow and actually understanding how it works.
And in 2026, learning the language of archery matters more than ever.
Compound archery is preparing for its Olympic debut at the LA28 Games, 3D archery continues to grow across the United States, and modern archers have more choices than ever when it comes to arrows, sights, rests, releases and tuning systems.
Whether you're choosing your first compound bow, setting up a recurve bow, preparing for a 3D shoot or trying to understand why your arrows keep landing left, this archery glossary explains the terminology you actually need.
You don't need to memorize everything at once.
Start with the terms that affect your equipment and shooting form most, then build your knowledge as your skills improve.
Why Archery Terms Matter More Than You Think
Understanding archery terminology isn't about trying to sound like an expert.
It helps you make better decisions.
When someone says your arrow may be underspined, your draw length looks too long or your cams are out of sync, understanding those terms gives you a starting point for solving the problem.
The same knowledge helps when shopping for equipment.
Instead of asking:
Which bow is the fastest?
You can start asking:
Does the draw length fit me?
Is the arrow spine correct?
What is the brace height?
How much let-off does the bow have?
Can I adjust the draw weight?
Does the riser accept ILF limbs?
Those are much more useful questions.
In fact, Archery 360 has continued publishing dedicated Archery Lingo guides in 2026 covering subjects such as draw length and arrow spine, reflecting how important these fundamentals remain for new and developing archers.
The 10 Archery Terms Every Beginner Should Learn First
If you're completely new to archery, start here.
The most useful terms to understand are:
Draw Length
Draw Weight
Arrow Spine
Anchor Point
Brace Height
Let-Off
Nocking Point
Arrow Rest
FOC
Dry Fire
Once these ten make sense, reading bow specifications becomes dramatically easier.
Now let's break them down.
Bow Parts and Compound Bow Terms
Riser
The riser is the central body of the bow.
It includes the grip and provides mounting points for components such as the sight, arrow rest and stabilizer.
Compound bow risers are commonly made from aluminum or other lightweight metals, while traditional recurves and longbows may use laminated hardwoods or composite materials.
The riser plays an important role in stiffness, balance and overall bow feel.
Limbs
The limbs are the flexible upper and lower sections of the bow.
When you draw the bowstring, the limbs bend and store energy.
When the string is released, that stored energy helps propel the arrow forward.
Modern limbs may incorporate fiberglass, carbon, wood laminates, foam cores or other composite materials.
On many takedown recurve bows, limbs can be replaced to change draw weight.
Bowstring
The bowstring connects the limbs and transfers stored bow energy into the arrow.
Strings should be inspected regularly for fraying, worn serving, damaged strands or unusual wear.
Bowstring condition can affect both safety and consistency.
Cams
Cams are the rotating wheels found on a compound bow.
Their shape controls how the bow's draw weight changes during the draw cycle.
They also help produce one of the compound bow's defining characteristics:
Let-off.
Cam design can affect arrow speed, draw-cycle feel, valley length, back wall and tuning behavior.
Let-Off
Let-off is the reduction in holding weight once a compound bow reaches full draw.
Imagine a compound bow with:
70 lb peak draw weight
75% let-off
The theoretical holding weight at full draw would be approximately:
17.5 lbs.
This allows an archer to hold at full draw more comfortably while aiming.
Higher let-off isn't automatically better, however.
Some archers prefer more holding weight because it helps them maintain tension against the back wall.
Axle-to-Axle Length
Often abbreviated ATA, axle-to-axle length measures the distance between the two axle positions on a compound bow.
A typical specification might read:
32-inch ATA
Shorter compound bows can be easier to maneuver in blinds, tree stands or dense terrain.
Longer bows may feel more stable to some target archers.
Neither is automatically better.
Fit and intended use matter more.
Brace Height
Brace height is generally measured from the bowstring to the deepest point of the grip when the bow is at rest.
This measurement affects bow geometry and shooting behavior.
For recurve archers, brace height is also an important tuning measurement.
Changing string twists can alter brace height and may influence sound, arrow clearance and bow feel.
Always follow the manufacturer's recommended range.
Draw Length Explained
Draw length is one of the most searched and most misunderstood archery measurements.
For compound bows, the commonly used standardized measurement is taken from the nocking point to the pivot point of the grip, plus 1.75 inches.
Your wingspan can provide a useful estimate, but it should only be treated as a starting point.
Proper draw length ultimately depends on your shooting form and body geometry.
A draw length that is too long can contribute to:
Poor shoulder alignment
Inconsistent anchor position
Excessive string contact with the face
Difficulty aligning the peep
Unstable shooting form
A draw length that is too short can create different alignment and anchor problems.
Archery 360 highlighted this again in its May 2026 guide, noting that even a relatively small draw-length error can negatively affect shooting form and accuracy.
One important detail beginners often miss:
Draw length and arrow length are not the same thing.
Arrow length depends on factors including draw length, rest position and how much shaft extends beyond the riser at full draw.
Draw Weight
Draw weight describes how much force is required to draw the bow.
For a recurve or traditional bow, the holding weight generally continues increasing as the archer draws farther.
Compound bows work differently.
They reach their peak weight during the draw cycle, then the cams reduce holding weight as the bow reaches full draw.
That is why a 50 lb recurve and a 50 lb compound can feel dramatically different.
Beginners should not automatically choose the heaviest bow they can physically pull.
A bow that is too heavy often causes poor form.
Good archery begins with control, not maximum draw weight.
Anchor Point
Your anchor point is the repeatable position your drawing hand, string and face reach at full draw.
For compound shooters, common reference points can include the release hand against the jaw, the nose touching the string and proper peep alignment.
Recurve anchor positions vary depending on shooting style.
The exact anchor may differ between archers.
The important part is repeatability.
Draw Cycle
The draw cycle describes how a compound bow feels as you pull the string from rest to full draw.
Archers often describe bows as having a:
Smooth draw cycle
Aggressive draw cycle
Stiff draw
Progressive draw
A fast compound bow isn't necessarily pleasant to draw.
For many archers, a smooth and repeatable draw cycle matters more than gaining a few extra FPS.
Valley
The valley is the section near full draw where a compound bow transitions into its reduced holding weight.
A generous valley can feel comfortable and forgiving.
A short or aggressive valley may try to pull the shooter forward if back tension relaxes.
This is one reason two compound bows with similar speed and let-off can feel completely different.
Back Wall
The back wall is the stopping sensation an archer feels when a compound bow reaches full draw.
A firm back wall provides a clear reference point.
Target archers often pay close attention to back-wall feel because it can affect consistency and release execution.
Arrow Spine Explained
If you're researching arrows, spine may be the most important word to understand.
Arrow spine refers to shaft stiffness.
With common carbon-arrow spine ratings:
300 spine is generally stiffer than 400 spine.
400 spine is generally stiffer than 500 spine.
Selecting the right spine depends on several factors, including:
Draw weight
Arrow length
Point weight
Bow type
Cam characteristics
Archery 360's 2026 arrow-spine guide emphasizes that draw weight, arrow length and point weight all affect the recommended spine.
One particularly important beginner mistake is confusing arrow length with draw length.
They are related, but they are not automatically the same measurement.
Static Spine vs Dynamic Spine
Static spine is the standardized stiffness rating assigned to the shaft.
Dynamic spine describes how the arrow behaves when actually launched from your bow.
Dynamic spine can change when you change:
Arrow length
Point weight
Draw weight
Insert weight
Bow efficiency
That means a shaft labeled 400 spine can behave differently depending on how you build the finished arrow.
Why Micro-Diameter Arrows Are Getting Attention in 2026
Arrow diameter has become a major equipment topic.
Several new 2026 arrow launches emphasize 4 mm, 5 mm and other smaller-diameter shafts designed to reduce exposed surface area and improve performance in crosswinds. Manufacturers are also offering more insert, collar and component combinations, making custom arrow building increasingly common.
This makes terms such as the following increasingly useful for modern bowhunters and target shooters:
Micro-diameter arrow
Insert
Outsert
Collar
GPI
FOC
Arrow spine
But smaller diameter alone doesn't guarantee better accuracy.
Correct spine and clean arrow flight still come first.
GPI
GPI means Grains Per Inch.
It describes how much the bare arrow shaft weighs for every inch of length.
For example:
An 8.5 GPI shaft weighs approximately 8.5 grains per inch before adding the nock, insert, point and vanes.
GPI is not the same as total arrow weight.
GPP
GPP means Grains Per Pound.
It compares total arrow weight with bow draw weight.
For example:
350-grain arrow
50 lb bow
350 ÷ 50 = 7 GPP
Always follow the bow manufacturer's minimum arrow-weight recommendations.
FOC
FOC means Front of Center.
It describes how far forward the arrow's balance point is compared with its physical center.
FOC can influence arrow stability, broadhead flight and penetration characteristics.
However:
More FOC isn't automatically better.
Arrow setup should always be considered as a complete system.
Fletching
Fletching refers to the feathers or plastic vanes located near the rear of an arrow.
Their purpose is to stabilize the arrow during flight.
Common configurations include straight, offset and helical fletching.
Vane size and configuration may vary depending on whether the arrow is intended for target shooting or broadhead use.
Nock
The nock is the component on the rear of the arrow that connects to the bowstring.
Correct nock fit is important.
A nock that grips the string too tightly or too loosely can affect consistency.
Insert
An insert fits inside the front of many carbon arrow shafts and provides the threaded connection for the arrow point.
Changing insert weight can change both total arrow weight and FOC.
Field Point vs Broadhead
A field point is primarily designed for target practice.
A broadhead is primarily designed for bowhunting.
Broadheads include fixed-blade, mechanical and hybrid designs.
Bowhunters should always verify local hunting regulations and tune their equipment before hunting.
Bow Tuning Terms Every Archer Should Know
Understanding tuning terminology can save you hours of frustration.
A bow may appear correctly assembled while still needing adjustments to improve arrow flight.
Paper Tuning
Paper tuning involves shooting an arrow through paper and examining the tear.
The tear gives information about how the arrow is leaving a compound bow.
Paper tuning can help identify issues involving rest position, nock height, cam lean or shooter input.
It is best treated as a diagnostic starting point rather than the final definition of a perfectly tuned bow.
Bare Shaft Tuning
Bare shaft tuning compares unfletched arrows with fletched arrows.
It is especially popular among recurve and traditional archers.
Bare shaft results can help diagnose arrow spine, nocking-point height and center-shot problems.
Center Shot
Center shot describes the horizontal relationship between the arrow, bowstring and riser.
On a compound bow, establishing a reasonable center-shot position creates a starting point for further tuning.
On recurves, center shot works together with arrow spine and the plunger.
Cam Timing
Cam timing refers to whether a compound bow's cams reach the correct positions at full draw.
Poor timing can affect:
Draw feel
Back wall
Nock travel
Arrow flight
Consistency
Cam Lean
Cam lean describes a cam that sits at an angle rather than perfectly vertical relative to its designed path.
A small amount may be normal on some bow designs.
Excessive lean can contribute to tuning problems.
Tiller
Tiller is an important recurve tuning term describing the relationship between the upper and lower limbs.
Many ILF risers allow tiller adjustment.
Tiller can influence the way the bow reacts during the shot.
Plunger
A plunger, sometimes called a cushion button, is widely used in Olympic recurve and barebow setups.
It provides adjustable lateral pressure against the arrow.
Plunger tuning works together with:
Arrow spine
Center shot
Arrow rest position
What Does ILF Mean in Archery?
ILF stands for International Limb Fitting.
It refers to a widely used interchangeable recurve limb attachment system.
ILF allows compatible limbs and risers from different manufacturers to be combined, giving archers more flexibility to change draw weight or upgrade equipment.
For target recurve archers, ILF is one of the most important equipment terms to understand.
Compound Bow vs Recurve Bow
A compound bow uses cams and cables to create let-off at full draw.
Compound bows are widely used for bowhunting, target archery and 3D archery.
A recurve bow uses curved limbs without compound cams.
Recurve bows are used for Olympic target archery, barebow, traditional shooting, recreational archery and hunting where permitted.
Both can be highly accurate.
They simply achieve that accuracy through different equipment systems.
Why Compound Archery Is a Bigger Topic Heading Toward LA28
Compound archery has received major attention since the announcement that the compound mixed team event will make its Olympic debut at the Los Angeles 2028 Games.
It will be the first new bowstyle added to the Olympic archery program since archery returned to the Games in 1972.
The LA28 qualification pathway was released in 2026, with 12 compound mixed teams set to qualify for the Olympic event.
For new archers, this makes terms such as:
Compound bow
Let-off
Cam timing
Draw length
Peep sight
Release aid
even more relevant as interest in compound competition continues to grow.
What Is Barebow Archery?
Barebow generally refers to recurve archery without a conventional bow sight.
Modern competition barebow isn't simply a completely bare riser.
Depending on competition rules, archers may use equipment such as:
Plungers
Arrow rests
Riser weights
Many barebow archers also use a technique called string walking, moving their string hand to different positions below the arrow to compensate for distance.
What Is 3D Archery?
3D archery involves shooting lifelike foam animal targets placed throughout natural terrain.
Targets may appear at different:
Distances
Angles
Heights
Lighting conditions
The discipline tests more than perfect shooting form.
It also challenges distance judgment, terrain management and adaptability.
3D archery continues to receive increasing attention in the United States, with USA Archery supporting expansion of local 3D programs.
The topic is especially timely in September 2026.
The World Archery Field Championships take place in Yankton, South Dakota from September 22–27, followed by the World Archery 3D Championships from September 28–October 3. It is the first time the two championships are being staged consecutively at the same location.
For newer archers searching for something beyond a flat target range, 3D archery is one of the most interesting disciplines to explore.
What Is Field Archery?
Field archery takes place on outdoor courses where targets are positioned across varying terrain.
Archers may face:
Uphill shots
Downhill shots
Marked distances
Unmarked distances
Uneven footing
Changing light
USA Archery describes field competition as a test of precision, adaptability and endurance across natural terrain.

A measurement of arrow speed.
GPI — Grains Per Inch
Weight of an arrow shaft per inch.
GPP — Grains Per Pound
Total arrow weight compared with bow draw weight.
FOC — Front of Center
The forward balance percentage of an arrow.
ILF — International Limb Fitting
A common interchangeable recurve limb system.
DL — Draw Length
Distance measurement associated with the archer and bow setup.

How to Read a Compound Bow Specification
You may see a product listing that looks something like this:
30–70 lbs / 19–31" DL / 32" ATA / 80% Let-Off / 330 FPS
Once you know the terminology, it becomes easy to understand.
30–70 lbs = Adjustable draw-weight range
19–31" DL = Draw-length range
32" ATA = Axle-to-axle length
80% = Approximate let-off
330 FPS = Advertised speed under the manufacturer's specified test conditions
This is why learning basic archery terminology makes shopping significantly easier.
Does Higher FPS Mean a Better Compound Bow?
Not necessarily.
Bow speed is one specification.
It does not tell you:
How well the bow fits you
How comfortable the draw cycle feels
How easy it is to tune
How stable it feels at full draw
How accurately you can shoot it
A bow that is slightly slower but fits your body correctly may produce better real-world accuracy.
Is More Draw Weight Better?
No.
More draw weight doesn't automatically make you a better archer.
Excessive draw weight can cause:
Raised shoulders
Collapsed form
Poor anchor consistency
Trigger punching
Reduced practice time
Beginners should select a draw weight they can control repeatedly with good form.
Is a Lower Arrow Spine Number Better?
No.
A lower spine number generally means a stiffer shaft.
That does not mean it is better.
You need the correct spine for your bow setup.
A shaft can be too weak or too stiff.
Use the arrow manufacturer's spine chart as your starting point.
Is Higher Let-Off Better?
Not always.
Bowhunters may appreciate high let-off because it allows them to remain at full draw with less holding weight.
Some target shooters prefer more holding weight because it gives them stronger feedback against the back wall.
The right choice depends on shooting style and preference.
Frequently Asked Archery Questions
What archery terms should a beginner learn first?
Start with draw length, draw weight, arrow spine, anchor point, brace height, nocking point, let-off, arrow rest, FOC and dry fire.
These terms affect bow fit, arrow selection, shooting form and safety.
What does spine mean on an arrow?
Arrow spine describes shaft stiffness.
The correct spine depends primarily on your draw weight, arrow length, point weight and bow setup.
What is the difference between draw length and arrow length?
Draw length describes the distance the bow is drawn based on the archer and bow geometry.
Arrow length describes the physical shaft length.
They are related but are not necessarily identical.
What does 70 lbs mean on a compound bow?
It normally refers to peak draw weight.
Because of let-off, a compound archer holds considerably less weight once the cams roll into full draw.
What does 80% let-off mean?
It means the bow reduces approximately 80% of its peak draw weight at full draw under its designed setup.
A 70 lb bow with 80% theoretical let-off would leave roughly 14 lbs of holding weight.
What is a good arrow spine for a 50 lb bow?
There isn't one universal answer.
Arrow length, point weight and bow type also matter.
Always start with the shaft manufacturer's spine chart.
What does IBO speed mean?
IBO speed is a standardized reference used to compare compound-bow performance under specified test conditions.
Your actual arrow speed will usually differ because your draw length, arrow weight, draw weight and accessories are unlikely to exactly match the test configuration.
What is the safest rule every beginner should know?
Never dry fire a bow.
Always inspect arrows before shooting and follow the equipment manufacturer's instructions.
Learn the Language, Then Learn Your Bow
Archery terminology can seem complicated at first.
But every term describes something practical.
Draw length helps your bow fit your body.
Arrow spine helps your arrow behave correctly.
Brace height affects bow geometry.
Let-off explains why a compound bow becomes easier to hold at full draw.
Cam timing helps a compound bow work consistently.
FOC helps describe arrow balance.
Once you understand those concepts, archery equipment becomes much easier to evaluate.
You stop buying equipment based only on the biggest FPS number or highest draw weight.
Instead, you start asking whether the bow, arrow and accessories actually work together.
That's when archery begins to make much more sense.
Whether you're preparing for your first range session, exploring 3D archery, following the road to LA28 or building your next bow setup, learning the language is one of the best investments you can make in your shooting.
