# Why won't Storage Studio accept my bucket name?

Bucket names follow rules set by the storage providers, not by Storage Studio: 3 to 63 characters, only lowercase letters, numbers, hyphens and dots, starting and ending with a letter or number.

Capital letters are the usual surprise — "MacBook-Pro" won't work but "macbook-pro" will. Storage Studio checks the name as you type and tells you exactly what's wrong, so you find out there rather than when the first backup fails.
