Mailing labels

Address label size

Small mailing labels look simple, but margin drift and cramped text show up on them faster than on larger formats.

Common default2.625 x 1

A practical starting point for envelope labels.

Main failure pointText crowding

Long lines look bad before the stock itself becomes wrong.

Best testOne real envelope proof

That tells you whether the alignment and spacing feel clean.

Quick check

What matters most here

Readable address labels are mostly about line count, font size, and printer alignment. The stock size is only one piece of the job.

  • 2.625 x 1 is the familiar mailing-label reference size for short address blocks.
  • If the address runs long, give the text more width before you reduce the font too far.
  • Return labels need less room, but they still need clean margins so the print does not feel cramped.

The label can fit the envelope and still feel crowded if the font is too small or the printer is not aligned cleanly.

Common questions

What size is a standard address label?

2.625 x 1 is a common starting point for address labels, especially on office sheet formats. It is not the only workable size, but it is the familiar default.

Can I use the same size for return labels?

Yes, but return labels often need less room. If the line count is short, a smaller format can still work cleanly.

What causes address labels to look messy?

Usually crowded text, poor alignment, or trying to squeeze long address lines into a label that is technically big enough but visually too tight.
