Paper Weights

Paper weights can be very confusing. We would like to offer a very general understanding of paper weights. This is not technical, but we will associate common weights with everyday items you may come in contact with. Here at Cutcardstock, we deal with two basic weights: TEXT WEIGHT and COVER WEIGHT. These two identifiers are probably the most important factors when you are purchasing a sheet of paper for your project. Please note that 80# text weight is a paper weight and 80# Cover weight is a card stock; although they have the same number marking them, they are two completely different papers.

    Paper and Envelope Sizes

    It's important when choosing paper, card stock, and envelopes to make sure you get compatible sizes. We recommend consulting the info below and double checking the sizing of items in your order to make sure that you avoid having to cut things down later, or simply not having something fit together.

    • Envelopes are almost always converted from text weight paper. The heavier the weight number, the heavier the envelope. A basic economy envelope will be converted from 20/50# paper. A nicer Invitation Envelope may be converted from 80# Text weight paper. More information on Paper weights can be found here.
    • Announcement Envelopes such as A1, A2, A6, A7 and A9, generally have a square flap.
    • We also sell Announcement envelopes that have a long triangular flap, these are called Euro Flap or deep flap envelopes.
    • Baronial envelopes have a pointed flap.
    • The sizing for Square Envelopes match their name. For instance, a 6 inch square envelope measures 6"x6".
    • PLEASE NOTE: Enclosures for Square Envelopes must be at least ¼ “ smaller than the envelope size. The invitation size for a 6 inch square envelopes would need to be 5.75 inches by 5.75 inches or smaller (We recommend a 5.5" square invitation for a 6" square envelope). A 6 inch square envelope will not hold a 6 inch square invitation.
    • A handy Guide for choosing your perfect invitation envelope can be found at the CutCardStock Blog.
    • Be sure to check United States Postal Service for additional costs and sizing restrictions for specialty envelopes.
