FAQs

What is the standard #10 window envelope size?

A #10 window envelope is 4-1/8" × 9-1/2". Our #10 double window and single window options align with common business check and statement layouts.

What’s the difference between double window and single window envelopes?

Double window envelopes show recipient and return address blocks. A single envelope with a window typically shows only the recipient address.

Should I choose self-seal or moisture-seal?

Self-seal (peel & seal) is fastest for high-volume mailings. Moisture-seal is the classic, budget-friendly option.

Do you have options for QuickBooks or ADP payroll?

Yes. Pick our QuickBooks/Quicken tight-fit designs for Intuit layouts and ADP payroll #10 double window envelopes for checks and pay advice.

Do you carry #9 window envelope and large window envelopes?

Yes. We offer #9 window envelope styles for compact layouts and large window envelopes (taller window placement) for specific forms.
