Make a powerful first impression before your letter is even opened. Custom-printed #10 business envelopes showcase your brand the moment your mail is seen.

Upload your own artwork or create a design in minutes with our easy online design tool. Businesses of every size use custom envelopes to build a polished, professional image without extra hassle.

Each envelope measures 9.5″ × 4.125″ and features premium 24# white wove stock, giving your mail a crisp look and quality feel.


Envelope Styles for Every Business Need

Choose the envelope style that fits your mailing purpose:

  • Regular (No Window)

  • Left Window

  • Security (Interior Tint)

  • Security Window

  • Peel & Seal Closures

Security envelopes include a blue interior pattern that helps protect sensitive information. Simply select this option under “Paper Type” when ordering.


Standard Window Placement for Easy Mailing

We position windows to align perfectly with standard business documents and mailing requirements.

  • Window Position: 7/8″ from the left edge and 1/2″ from the bottom

  • Window Size: 4-1/2″ × 1-1/8″

  • Leave a 1/16″ clear space around all window edges

These precise specifications help your addresses show correctly and reduce the risk of mailing delays.


Simple and Accurate Artwork Placement

We place your artwork based on how you set up your file:

  • Include crop marks and we print your design exactly where you position it

  • Skip crop marks and we place your artwork in the upper left corner

This process keeps printing clean, sharp, and consistent — even with simple layouts.


Required Margins for Best Results

Keep all artwork inside a safe print area to ensure the best outcome. Maintain a minimum 1/4″ margin on all sides of the envelope. This spacing helps prevent trimming issues and protects the overall look of your design.


Please Note About Color

Screen colors can look different from printed colors. Because monitors vary in calibration, slight color differences may appear in the final product.


Why Choose Custom #10 Envelopes?

Businesses rely on #10 envelopes more than any other size. A standard letter folds neatly into thirds, making these envelopes perfect for invoices, statements, marketing letters, and everyday correspondence.

Full-color printing turns every envelope into a branding opportunity. Whether you order a small batch or a large run, you get professional results at an affordable price.

We print every envelope on premium white wove stock so your mail looks professional — and feels that way too.
