The formula is: Total Length = (Grip Length × Grip Circumference) ÷ (Tape Width × (1 − Overlap%)) + Extra for Securing. Each complete wrap around the handle covers a distance equal to the grip circumference. The tape advances along the handle by its effective width (tape width minus the overlapped portion). Dividing the total grip length by this effective width gives the number of wraps needed, and multiplying by the circumference yields the total tape length required.

Most players prefer 25%–50% overlap. A 33% overlap (about 1/3 of the tape width) is a great all-around choice — it provides good cushioning without using too much tape. A 50% overlap creates a thicker, more cushioned feel but uses more tape. A lighter 10–15% overlap gives a thinner, closer-to-the-handle feel preferred by some advanced players who want maximum feel.

Most overgrip rolls are between 98 cm and 120 cm (approx. 38–47 inches). Wilson Pro Overgrip is 110 cm, Yonex Super Grap is 120 cm, and Tourna Grip is about 98 cm. One roll is typically enough for one racket handle with moderate overlap. If you prefer heavy overlap or have an extra-long handle, you may need part of a second roll.

Yes! Tennis grips tend to be thicker (circumference ~104–117 mm / 4⅛–4⅝ inches) and longer (~18 cm). Badminton grips are thinner (~83–92 mm / G3–G5) and slightly shorter (~17 cm). Squash and pickleball grips fall in between. Selecting your sport above automatically sets realistic default values to get you started quickly.

If your required length exceeds a standard roll (e.g., 110 cm), it's usually because of high overlap percentage, a thick grip circumference, or a long wrap length. You can reduce overlap, use a wider tape, or accept that you'll need part of a second roll. The tool will alert you with a roll estimate.

This calculator assumes a cylindrical handle for simplicity. Real racket handles taper slightly (narrower at the top), which means the actual circumference decreases as you wrap upward. In practice, the cylindrical model gives a very close estimate — within 3–5% of real-world needs. The "Extra for Securing Ends" field accounts for the finishing tuck at the top.

Wrap a flexible measuring tape around the middle of the grip (or use a piece of string and measure it against a ruler). For tennis rackets, common sizes are stamped on the butt cap (e.g., "4 3/8" means 4⅜ inches). For badminton, grip sizes are often marked as G3, G4, or G5 — G4 ≈ 86 mm, G5 ≈ 83 mm circumference.

Overgrips are designed for single use and typically lose their tackiness and cushioning after a few sessions. Some players flip the overgrip upside down to use the clean underside once more, but this is not ideal for performance. A fresh overgrip provides the best sweat absorption and grip security.

A replacement grip is thicker (1.5–2.5 mm) and directly replaces the original grip on the bare handle. An overgrip is thinner (0.4–0.6 mm) and wraps over the existing grip to add tackiness, sweat absorption, and slight cushioning without significantly changing the grip size. Overgrips are changed more frequently — often every few matches.

Wrap with moderate, even tension — tight enough that the tape lies flat without wrinkles, but not so tight that it stretches thin or tears. Stretching the overgrip too much reduces its cushioning ability and can cause premature wear. A consistent overlap (e.g., 33%) with steady tension yields the best results.
