How to Measure Bow Draw Weight | Accurate Poundage at Home

Measuring bow draw weight correctly takes a bow scale, a full draw to your anchor point, and a stable reading of the peak force in pounds.

A bow scale answers the question in about a minute. You attach it to the bowstring, draw to your normal anchor position, and read the peak number on the display. The process sounds simple, but small differences in your draw length and form can shift the reading by several pounds. Here’s the exact procedure for getting a number you can trust, whether you’re checking a recurve, longbow, or compound.

How to Measure Bow Draw Weight: The Standard Method

You need a bow scale or any weight scale that attaches securely to the bowstring. Digital luggage scales work well because they hook onto the string and show the force in pounds. ATS Bow’s coaching guide describes the standard workflow clearly.

1. Attach the scale to the bowstring at the nocking point where your arrow normally sits.
2. Make sure the scale doesn’t block your grip and that the display faces you so you can read it at full draw.
3. Draw the bow slowly to your normal anchor position, matching your real shooting form as closely as possible.
4. Hold for a moment and read the peak weight shown on the scale.
5. Lower the bow gently. Never let go of the string while the scale is under tension.
6. Repeat two to five times and average the readings, or note the highest stable number if you’re checking peak draw weight.

The measurement varies with your technique, which is why several sources recommend multiple readings. If you’re 1-2 inches off your typical anchor, the number will shift. Match the position to your actual shooting form, not a position that happens to be comfortable with a scale attached.

The Standard 28-Inch Reference Point

For recurve and longbow archers, draw weight is referenced to a 28-inch draw length. A bow marked “34# @ 28” means it delivers 34 pounds of force when drawn to 28 inches from the string rest to the pivot point. ATS Bow’s draw weight and draw length guidance explains how these two measurements work together.

Compound bows work differently. The relevant number is the peak weight during the draw cycle, not the weight at full anchor. Compound cams have let-off that drops the holding weight dramatically at full draw. A 60-pound compound bow might hold at only 12-15 pounds once you’re past the peak. When you test a compound, draw through the cycle slowly and note the highest number the scale shows before let-off kicks in.

Draw weight always varies with draw length, so a bow marked at 28 inches can’t be assumed to pull the same weight at a 30-inch draw. Anyone with a draw length longer or shorter than 28 inches will feel a noticeably different poundage.

How Many Times Should You Measure?

Take at least two or three measurements and compare them. Bow Sports’ FAQ notes that readings can vary with technique, so a single draw can mislead you. If your numbers swing more than 2 pounds, check your anchor position and the scale attachment before redrawing. The most consistent readings come from a smooth, controlled draw without jerking the string.

What the Numbers Mean for Your Setup

Once you have a reliable poundage, you can match it to your arrows, limbs, and tuning. The bow’s marked weight assumes a specific draw length, so your measured weight tells you what the bow actually delivers in your hands. That’s the number that matters for spine selection and safe arrow matching.

This is also the moment to decide if your setup needs adjusting. If a bow scale reads lower than expected, check for a loose limb bolt or a string that has stretched. If you’re shopping for a reliable archery draw weight scale, look for one with a hook that fits your bowstring type and a display you can read while holding the bow.

Safety comes first when testing. Point the bow in a safe direction, never dry-fire it, and release the string slowly back to brace height instead of letting it snap forward against the scale.

Final measurement tip: measure on a day when you’re rested, use the same anchor every time, and write the averaged number down. That’s the poundage your bow actually delivers, and it’s the one every future setup decision should reference.
