5 1/4 x 5 1/4 Square Envelopes

Square cards gain a distinctive presentation with a 5 1/4 x 5 1/4 inch envelope sized for wedding invitations, greeting cards, holiday correspondence, announcements, and business mailings. The size provides sufficient space for printed stationery while remaining compact for smaller pieces. Its symmetrical shape also sets event and promotional mail apart from conventional rectangular envelopes.

Visual variety is a key part of this assortment, with white, natural, kraft, linen, metallic gold, navy blue, red, aqua blue, and clear styles available. These different papers and finishes can complement casual, formal, seasonal, or branded stationery. Matching the envelope to the enclosed card helps create a more cohesive finished piece.

Peel & Seal closures are especially useful for projects that involve repeated assembly, including invitations, greetings, promotional pieces, and customer mailings. This square size also suits event correspondence, announcements, and creative projects. Businesses and individuals can choose among different colors and finishes while keeping the same 5 1/4 inch size.
