Taping Calculator

This calculator answers a practical supply question: how much athletic tape a taping plan consumes, in rolls, and how long each application takes. The Joint dropdown sets the base figures — an ankle application uses 180 cm of tape and about 5 minutes of work, a knee 250 cm and 7 minutes, a wrist 120 cm and 4 minutes, and a shoulder 200 cm and 8 minutes. Tape Width then trims the per-application length: the standard 3.8 cm width applies a 0.95 factor to the base length, the wide 5.0 cm roll cuts it to 0.85 because each strip covers more area, and the narrow 2.5 cm roll leaves the base figure unchanged. Width affects only that length adjustment — it has no influence on the time estimate, which is looked up purely from the joint.

Rolls Needed multiplies the adjusted per-application length by your Number of Applications and divides by 500 cm, the assumed length of one standard roll, rounding up so a season plan always buys a whole extra roll rather than running short. That ceiling step means small changes in application count often leave the roll total untouched until you cross a 500 cm boundary; at the defaults, ten ankle applications take about 171 cm each for 1,710 cm total, which is four rolls. Not included: pre-wrap, underwrap, or waste from torn partial strips.
