Bubble Mailer Size Calculator

Size Guide · Bubble Mailers

Bubble mailers cushion your product on all sides, so you'll need a bit more room than a flat mailer. Enter your three dimensions and we'll factor in the padding for you.

The math, if you'd rather do it yourself

Bubble mailers wrap padding around all sides of your product, so the length needs to cover the thickness twice (front and back of the seal flap), and the width adds the thickness once for the side seam. We add a 1″ buffer so it fits without forcing.

Pick a NOYO size that meets or exceeds both numbers below.

Minimum length
Product length + product height × 2 + 1″
Minimum width
Product width + product height + 1″
