Quick Scoop

A queen is one of the most common mattress sizes for couples because it offers a good balance of sleeping space and room fit.

  • Standard queen dimensions: 60" x 80" (152 x 203 cm).
  • In feet, that’s roughly 5 ft x 6.7 ft.
  • Typical mattress thickness varies a lot, usually around 9"–16" depending on the model.

There are also a few related queen variants you may see:

  • California Queen: 60" x 84" (longer).
  • Olympic Queen: 66" x 80" (wider).
  • Split Queen: two pieces, each 30" x 80".

So if you’re shopping or measuring your room, you can safely assume a standard queen is 60 by 80 inches unless it’s specifically labeled as one of these variants.
