FAQ

Are the sizes exact?

These are the commonly used charts. Brands sometimes differ, so check the store's size chart.

How do I pick shoes by foot length?

Choose the “cm” system and enter your foot length to see the EU, US and UK sizes.

How do I convert a US clothing size to a European one?

Choose the category, women's or men's clothing, then the US system and your size. Calcie shows EU, UK, INT and the other systems all at once.

Does the “Sizes” mode work offline?

Yes. Calcie does all its math right on your device, so the mode works on a plane, on the subway and out of town. Nothing is sent to any server, and the answer appears instantly.

Is “Sizes” available on iPad and Mac?

Yes. On iPad the mode has its own layout with larger fields, and on a Mac with Apple Silicon Calcie runs in its iPad version and works from the keyboard. Your Premium purchase applies on every device signed in with your Apple ID.

How do I switch to the “Sizes” mode?

Open the modes menu, the icon at the top left of the calculator's main screen, and choose “Sizes”. Calcie remembers your choice: next time the app opens right in that mode.
