Draw Weight
“Draw weight” means the amount of force needed to pull a bowstring to full draw. This is commonly called the bow's poundage.
Calculating Draw Weight on a Vertical Bow
- Vertical bows measure draw weight in pounds.
- The simplest way to measure a bow’s draw weight is to use a scale that can hook onto the bowstring. Several bow draw weight scales are available that are designed for this purpose.
- Using a measuring device to draw the bowstring may make your draw shorter. Ensure you are bringing the bow to a 28” draw length.
- You can use a sufficiently long arrow and mark the 28” draw point on it so when taking measurements in the future, you can use this “ruler” arrow to save time.
Calculating Draw Weight on a Crossbow
- Crossbow draw weight is measured in Inch-pounds and requires a few extra steps compared to vertical bows.
- Inch-pounds are calculated by multiplying draw weight (see above) by the power stroke.
- Power stroke is the length between the crossbow's string in the rearmost (cocked) position and its resting (uncocked) position, measured in inches. It very roughly equates to draw length in a vertical bow.

Below is a mathless way to determine if your crossbow is legal for use in Amtgard combat. Consult the chart below and find your crossbow's power stroke. If your draw weight is equal or less than the associated value, it is legal. If it is greater, then the crossbow cannot be used.
