The math, if you'd rather do it yourself
Each dimension of the bag has to do two jobs: cover your product and wrap around its thickness. We add a small buffer so it actually fits and seals cleanly.
Pick a NOYO size that meets or exceeds both numbers below.
Minimum length
Product length + product height + 2″
Minimum width
Product width + product height + ½″
