#11 Regular Envelope Size

These #11 regular envelopes measure 4.5 by 10.375 inches and come in a box of 500. They suit offices, schools and mailrooms that need a standard business size for letters and invoices. The white sulphite stock is SFI certified with 92% brightness and a vellum finish. They are not intended for oversized documents or packages requiring larger formats.

28# Weight and 500-Count Capacity

The 28# paper weight provides enough rigidity for typical correspondence while keeping postage costs low. A single box holds 500 envelopes and a full carton contains 2500, giving ample supply for routine mailing runs. Heavier inserts or thick catalogues may exceed the comfortable capacity of this weight. Users sending bulky multi-page contracts may find the stock too light.

Diagonal Seam and Remoistening Seal

The diagonal seam construction adds strength across the flap area for reliable sealing. A remoistening adhesive activates with moisture so no tape or separate glue is required. The vellum finish accepts pen, pencil and most office printers without smudging. There is no window, so address labels or printed addresses must be applied to the face.

Questions about this item

Will the 4.5 x 10.375 inch #11 envelopes fit in my existing #10 envelope trays or folders?

These #11 envelopes measure 4.5 by 10.375 inches, which is larger than the standard #10 size, so they will not fit in trays or folders cut specifically for #10 dimensions.

How can I verify the 28 lb paper weight and 92% brightness after opening the box?

The SFI certified white sulphite stock has a vellum finish; the 28 lb basis weight and 92% brightness are mill specifications confirmed by the SFI certification on the box label.

Does the box of 500 include any moisture-activated seal strips, or must I buy separate adhesive?

Each envelope has a remoistening seal on the diagonal seam flap; no extra adhesive or seal strips are required.
