The USPS has announced they will be reducing the size of some free Priority Mail boxes and envelopes. Two Priority Mail envelopes and six Priority Mail boxes will be getting smaller, with the reductions ranging from 1/8" smaller in length on the Priority Mail Tyvek envelope to 2 1/2" smaller in width on the Priority Mail Regional Rate Box B.
