Arrow Trajectory Calculator

Model arrow drop by distance from your arrow speed and zero range. Full trajectory chart at 10, 20, 30, 40, 50, 60, and 80 yards, with sight-tape guidance for compound and crossbow setups.

๐ŸŽฏ Arrow Trajectory Calculator

Enter arrow speed and zero distance to see drop at every 10 yards out to 80. Assumes a level shot with no wind.

Formula (gravity-first model): Drop = ยฝ ร— g ร— tยฒ, t = distance รท speed g = 32.174 ft/sยฒ. Relative drop = drop(target) โˆ’ drop(zero). Real-world drop is typically 10โ€“20% higher at long distances due to drag.

โš™๏ธ How to Use This Chart for Sight Tape

  1. Set your 20-yard pin first. Confirm your 20-yard zero with a group of at least 5 arrows.
  2. Read the drop column at each distance. At 30 yards, for example, an arrow flying 275 fps drops roughly 3.9 inches relative to a 20-yard zero.
  3. Dial or hold. Use a multi-pin sight (adjust pin heights) or a single-pin slider (dial the yardage).
  4. Verify every distance on the range. The calculator gives you a starting point โ€” the range confirms your actual tape values.
  5. Re-run after any change. Arrow weight, tip weight, draw weight, or draw length change = new trajectory.

๐Ÿ“ Typical Real-World Drops (Reference)

These are commonly reported arrow drops at 40 yards from a 20-yard zero. Real drop depends on bow tune, arrow drag, and form.

Arrow SpeedDrop at 30 ydDrop at 40 ydDrop at 50 ydDrop at 60 yd
240 fps~4.9"~10.8"~19.4"~31.5"
260 fps~4.2"~9.2"~16.5"~26.8"
280 fps~3.6"~7.9"~14.2"~23.1"
300 fps~3.1"~6.9"~12.4"~20.1"
320 fps~2.8"~6.1"~10.9"~17.7"

Values are gravity-only estimates from a 20-yard zero. Real arrows drop 10โ€“20% more at long distance due to aerodynamic drag.

โ“ Frequently Asked Questions

Is this a full ballistic simulator?

No. This is a gravity-first model designed for sight-tape planning. Real arrow drop includes drag, which increases drop by 10โ€“20% at long distances. Use these values as a baseline, then confirm every distance on the range.

What is arrow trajectory?

Arrow trajectory is the curved path an arrow follows from the bow to the target. Because arrows travel much slower than bullets, trajectory is more pronounced, requiring holdover or sight adjustment at longer distances.

How much does arrow drop from 20 to 30 yards?

At typical compound speeds (270โ€“290 fps) and a 20-yard zero, drop at 30 yards is roughly 3.5โ€“4.5 inches. Heavier arrows and slower speeds increase this. Run the calculator above with your exact speed for a specific value.

Does this work for crossbow trajectory?

Yes. Enter your crossbow bolt speed. For a dedicated crossbow ballistic calculator with bolt weight and KE, use our crossbow ballistic calculator.

Why does my real drop not match the chart?

Three reasons: (1) aerodynamic drag is not modeled here, (2) arrow tune affects initial direction, and (3) your measured speed may differ from what is entered. Verify speed with a chronograph, then re-run.

Should I use MOA or inches?

Inches is easier for sight-tape work at hunting distances (20โ€“60 yards). MOA is useful for scope dialing or long-range target work. Both columns are provided.
