About this app

Size Guide converts shoe, clothing, bra, ring, hat and glove sizes between every major size system, instantly and offline. Pick a system, pull the tape to your size, and read it in all the others at once. Tap any row to make it the source.

SHOES
- Men, women and kids (toddler, little kid and big kid)
- US, UK, EU, Japan, Korea, China, Australia, Mexico and Brazil, plus foot length in cm and inches
- "I know my foot length": enter a measurement and get the right size in every system
- One master scale keeps men's and women's sizes consistent with each other

CLOTHING
- Women's tops and dresses: letter sizes, US, UK, EU, France, Italy, Japan, Australia and China
- Men's shirts by collar, suits and jackets by chest
- Jeans and trousers: waist × inseam in inches and cm, EU trouser sizes and US women's sizes
- Kids' clothing by age and height

BRAS
- Band and cup across US, UK, EU, France/Belgium, Australia/New Zealand and Japan
- A calculator that estimates your size from underbust and bust measurements (clearly marked as an estimate)

RINGS
- US/Canada, UK/Australia, EU/ISO, Japan/China, inner diameter and circumference
- On-screen ring sizer: calibrate your screen once with any bank card, then lay a ring on the circle to read its size

HATS AND GLOVES
- Hat sizes from head circumference (US, UK, EU and letter sizes)
- Glove sizes from hand circumference

MEASURE YOURSELF
Clear illustrated guides for foot length, height, chest, bust, underbust, waist, hips, inseam, neck, head, hand and ring finger. Enter each measurement on a real tape measure in cm or inches, and see which size it means.

MY SIZES
Save sizes and measurements for yourself and everyone you shop for. Each person's sizes show in every system, ready for buying a gift from another country, and you can share a person's size card as text. Measurements turn into size suggestions automatically.

HONEST ABOUT SIZING
The app uses widely published reference charts and the standards behind them (such as JIS, Mondopoint, BS 6820 and ISO 8653). Sizes vary between brands, so when a brand publishes its own chart, check it.

PRIVATE AND OFFLINE
No account and no internet connection needed. Your sizes and measurements stay on your phone.

ADS
Size Guide is free and ad-supported. It shows a small banner and, occasionally, a full-screen ad when you go back to the home screen after several conversions or after saving a profile, never while you are entering a size. You can watch a short video to pause full-screen ads for 24 hours.

Available in English and Indonesian.
