Sizes scale the name area from M using typical chest widths for Indian sportswear (kids 26 = 0.72 of M up to 3XL = 1.21). Your own pattern may differ; use your size chart where you can.
How to use the result
If a name only needs shrinking on kids sizes, keep your design as it is and reduce the letter height on those sizes. If it needs shrinking on M or L too, either widen the name area in the template or agree a shorter print name with the player, such as a surname only.
The 90% limit leaves a margin on each side so the name does not touch the seams or the edge of a number. Most printers use something similar.

| Basketball | 5 to 7.5 cm common | at least 20 cm | FIBA rules for numbers; names by shop practice |
| Cricket | 5 to 7 cm common | 15 to 22 cm common | Shop practice; check the league |
Questions
How is name width estimated?
Width is letters multiplied by letter height multiplied by the font's width ratio, plus letter spacing. Condensed sports fonts are usually 0.5 to 0.6 of their height per letter; regular fonts are about 0.65 to 0.75.
What letter height do football names use?
FIFA's equipment rules give 5 to 7.5 cm for names on the back. Many amateur leagues follow a similar range; check your league's rules.
