Bearring size

Phinx

I recently decided to work a bit on my old FS bike, but when i disassembled the bottom bracket, i managed to misplace my bearings and races for good. By bottom bracket is cup-and-cone type, but i'm hesitating on which size bearings and races to buy. I read that BB usually uses a 1/4 bearings. True or false?

Most bottom brackets use 11 1/4" balls on each side.
