Piece Size Tool

Letter or flat, before it changes your postage.

Piece Size Tool INPUTS Artwork PDF Finished size Fold Run RESULTS Detected size 6.00 in x 9.00 in Category Letter Aspect ratio 1.50 (machinable) Watch Under 0.25 in thick Preliminary estimate. Confirmed at USPS acceptance.

What it does

Upload a PDF and confirm which USPS size category the finished piece falls into, with the dimensions that decide it.

Why it matters

A fraction of an inch moves a piece from letter to flat pricing. Catching that before print is the difference between a budget that holds and one that does not.

How to use it

  1. Upload the artwork PDF
  2. Confirm the detected trim size
  3. Read the category and any warnings
