What is an archery sight tape?
A bow sight tape is a narrow adhesive strip marked with yardage increments that attaches to a single-pin adjustable sight's vertical track. As you move the sight housing up or down, the tape tells you exactly which position corresponds to which shooting distance — so you can dial your precise yardage in the field rather than relying on memorised pin gaps or guesswork.
Unlike multi-pin sights with fixed pins at preset distances (20, 30, 40, 50 yards), a sight tape combined with a single adjustable pin gives you a precise setting at any distance — including the 37-yard shot that falls between two fixed pins.
How sight tapes work
Every bow has a unique ballistic profile: the combination of arrow speed, arrow weight, and sight height above the arrow determines exactly how much the sight must move to compensate for trajectory drop at each distance. This calculator uses that profile to compute the required sight movement (in sight units) at every yardage from your zero to your maximum distance, then formats those positions as a printable tape.
The sight scale factor — why it matters
Different sight models use different mechanical ratios between physical movement and apparent angular movement. A sight with a 1.32× scale factor requires the housing to move 1.32 inches to produce 1 inch of vertical adjustment at your zero distance. Without accounting for your specific sight's scale, your tape marks will be offset at distance. Always check your sight's owner's manual for the scale factor (also called "tape ratio" or "multiplier").
| Sight / Brand | Typical Scale Factor | Notes |
|---|---|---|
| Basic single-pin sights | 1.00 | Trophy Ridge React Pro, Axcel, most entry-level |
| HHA Optimizer Lite | 1.10 | Check model-specific documentation |
| Spot Hogg Tommy Hogg / Hammerhead | 1.32 | Verify with Spot Hogg support for your exact model |
| Black Gold Pro / Spot Hogg Fast Eddie | 1.50 | High-ratio for very fine adjustments |
| Specialty Archery Pro / competition sights | 1.70+ | Competition sights with fine-vernier scales |
Scale factors vary within model ranges. Always verify in your sight's manual before printing a final tape.
Sight tape vs. multi-pin sight — which is right for you?
🎯 Multi-pin sight
Best for: Tree stand hunting, close-range shots (15–50 yards), beginners, and situations where you can't dial before the shot. Fixed pins mean instant reference — no adjusting under pressure.
📏 Single pin + sight tape
Best for: 3D archery, spot-and-stalk hunting, open country, and any situation where you range the target before shooting. Provides exact yardage at any distance, not just pin distances.
✅ When to choose a sight tape
You have time to range and dial before shooting. You shoot at variable distances (3D courses, western hunting). You want a single clean sight picture without multiple pins cluttering your view.
⚠️ When a sight tape is the wrong choice
You're in a tight stand with minimal movement time. You frequently encounter close, fast shots where dialling isn't possible. You shoot recurve or longbow (these almost always use instinctive or gap methods instead).
The critical difference: any distance vs. fixed distances
A 5-pin sight set at 20, 30, 40, 50, 60 yards has a significant dead zone — a shot at 45 yards means either aiming low on the 40-yard pin or high on the 50-yard pin, hoping you judge the gap correctly. A sight tape eliminates this. You range the target at 43 yards, dial to 43, and aim dead centre. For 3D archery, where distances are unknown and precise yardage estimation is part of the competition, sight tapes are standard.
How to apply and verify a sight tape
Step 1 — Generate and print your tape
Run this calculator with your chronographed arrow speed, total arrow weight, and correct sight scale factor. Print the resulting tape data. Most archers mark the measurements on a blank paper tape (sold by most archery sight manufacturers) using a sharp pencil and a ruler. Pre-printed tape sets (available from most archery retailers) work with sights that accept standard tape widths.
Step 2 — Set your zero
Sight in perfectly at your zero distance before applying the tape. This is your reference mark — the tape's "0" position. All other tape marks are calculated relative to this reference.
Step 3 — Apply the tape
Most adjustable sights have a tape slot alongside the vertical travel track. Slide the tape in with the zero mark aligned to the sight housing's indicator line when at your zero position. If your sight doesn't have a built-in slot, adhesive tape can be applied to the sight's housing or bracket — some archers use a thin strip of label paper.
Step 4 — Field verify at three distances
Before hunting season, verify your tape at three distances: your zero (should hit dead centre), a mid-range distance (e.g. 40 yards), and your maximum planned shooting distance. If the arrows hit high or low, adjust your entered speed up or down by 5 fps increments until the tape matches real-world impact. Even a perfectly calculated tape needs field verification — small differences in arrow lot, temperature, and altitude shift real-world results from the theoretical model.
Calibrating your sight tape — common errors and fixes
| What you observe | Likely cause | Fix |
|---|---|---|
| Arrows hit high at 40 yards, correct at 20 | Entered speed is too high (tape marks too compressed) | Decrease entered speed by 5–10 fps, regenerate tape |
| Arrows hit low at 40 yards, correct at 20 | Entered speed is too low (tape marks too spread) | Increase entered speed by 5–10 fps, regenerate tape |
| Error grows larger at longer distances | Arrow weight entered incorrectly | Weigh your complete arrow (with broadhead) and re-enter weight |
| Error same at all distances | Zero not verified / scale factor wrong | Re-verify zero, then double-check sight scale factor in manual |
| Tape marks correct in warm weather, off in cold | Temperature effect on arrow speed (cold strings are stiffer) | Generate a separate tape for cold-weather hunting at –5 to –10 fps |
A difference of 10 fps in entered speed changes your 60-yard tape mark by approximately 1.5–2 inches. Chronograph your setup in the conditions you hunt (similar temperature, same hunting arrows) for best accuracy.

Sight tape calculator FAQs
What is a bow sight tape?
A bow sight tape is a narrow marked strip that attaches to a single-pin adjustable sight's vertical track. It shows you exactly which position on the track corresponds to which shooting distance, so you can dial your precise yardage in the field. Unlike fixed multi-pin sights, a sight tape gives you an exact setting at any distance — including the 37 or 43 yard shots that fall between fixed pins.
How is a sight tape different from sight marks generated by the Sight Mark Calculator?
The Sight Mark Calculator generates pin position data for multi-pin sights or basic relative adjustments for single-pin setups, in general inches-of-movement units. This sight tape calculator accounts for your specific sight's scale factor, generating tape marks in the actual mechanical units your sight uses — so the output maps directly to the position indicator on your physical sight housing. It also produces a visual tape strip for direct reference, and includes a pin gap chart for field comparison at common hunting distances.
Do I need a chronograph to use this calculator?
A chronograph gives the most accurate results. Without one, use our Arrow Speed Calculator to estimate fps from draw weight, draw length, and arrow weight, then enter that estimate here. A 10 fps error moves your 60-yard tape mark by approximately 1.5 inches. A basic archery chronograph costs $100–200 and pays for itself the first season.
How do I find my sight's scale factor?
Check your sight's owner's manual — it's usually listed as "tape scale," "tape ratio," or "sight multiplier." If it isn't in the manual, search "[brand] [model] sight tape scale factor." Common values: 1.00 for basic sights, 1.32 for Spot Hogg Hammerhead, 1.50 for Black Gold Pro. If you genuinely can't find it, use 1.00 and field-verify your tape against known distances — adjust speed input until the tape matches.
Can I use this tape for recurve or traditional archery?
Recurve and longbow archers almost always shoot with instinctive aiming, gap shooting, or string walking rather than adjustable sights with tape marks. However, barebow competitors who use movable sights can use this calculator — select "Recurve" as your bow type and enter your measured arrow speed. The lower speeds typical of recurve archery will produce larger spacing between tape marks, which is correct.
What happens if my tape is accurate at 20 and 40 yards but off at 60?
A tape that's correct at two points but drifts at longer distances usually indicates an arrow weight entry error. The weight of the arrow affects how quickly it decelerates (ballistic coefficient), which has relatively little impact at short distances but compounds at 60+ yards. Reweigh your complete arrow including broadhead or field point and re-enter the accurate weight.
How often do I need to regenerate my sight tape?
Regenerate whenever you change arrow weight (different broadheads, different shafts), change arrow speed (new strings, draw weight adjustment), or switch bow setups. A tape is also less accurate on cold hunting days than it was when verified in warm conditions — consider generating a cold-weather version at 5–10 fps slower for autumn and winter hunting.
