Every business envelope type serves a specific purpose. From #10 commercial envelopes for daily correspondence to 9×12″ catalog envelopes for marketing materials — this guide covers every standard business envelope style we manufacture, with custom options for each.
The #10 envelope (4⅛” × 9½”) is the standard business envelope worldwide. It fits a letter-size document folded in thirds — making it the workhorse of invoices, statements, and everyday business correspondence. We manufacture custom #10 envelopes with logo printing, window options, and your choice of closure type.

Standard business envelope without window. Used for general correspondence, letters, and marketing mail. Most economical option for everyday mailing.
One window showing the recipient address printed on the enclosed document. Eliminates the need for separate address labels. Perfect for invoices and statements.
Two windows — one for the recipient address, one for the return address. Both visible through the envelope. Common for reply envelopes and billing cycles.
Custom window envelopes are essential for businesses that mail invoices, statements, and forms. The window eliminates the need to print addresses on the envelope itself — the address on the enclosed document shows through. We manufacture windows in any size, position, and shape to match your document layout precisely.
| Window Type | Description | Common Size | Best For |
|---|---|---|---|
| Single Window | One opening for recipient address | 1⅛” × 4½” (standard) | Invoices, statements, business mail |
| Double Window | Recipient + return address windows | Custom per document | Reply envelopes, W-2, billing |
| Custom Position | Window at any coordinate | Fully custom | Forms with unique layouts |
| Custom Shape | Rounded corners, oval, branded | Fully custom | Premium branding |
