FootGauge: Shoe Size

Buying shoes online and not sure of your size? FootGauge prints a true-size foot-length ruler you can stand on at home, then turns your length into US Men's, US Women's or EU sizes.

Tap Print Measure Chart and print the two-page PDF at 100%. Check the scale with a real credit card, cut along the HEEL line, tape page 2 on at the ALIGN line, put the heel edge against a wall and mark your longest toe. Enter the length in the app to see your size in all three systems.

• TRUE-SIZE RULER TO 340 MM — millimeter ticks start at 0 on the HEEL line and run across two Letter pages, long enough for any adult foot.
• CREDIT-CARD SCALE CHECK — a card-size outline on the sheet; if a real card doesn't match its edges, your printer scaled the page and you should reprint at 100%.
• SIZE FINDER — type your foot length in mm or inches and see the matching US Men's, US Women's and EU size side by side.
• US MEN'S, US WOMEN'S OR EU — US Men's 6–14 and US Women's 5–12 in half sizes, or EU 35–48, marked right on the ruler.
• SIZE TABLE — every size with its approximate foot length in millimeters and inches.
• PRINT, SHARE OR SAVE — print with AirPrint, share the PDF or save it to Files.

FootGauge is a shopping aid only. Sizes are approximate and vary between brands and shoe styles, so always check the retailer's own size guide. It is not a medical device and does not assess foot health — for fit problems or foot pain, see a professional.
