FAQs

Start with what you’re putting inside. If you already know the size you need, you can shop by envelope size. If you’re not sure, our Envelope Size Guide can help you   compare common sizes and styles.  For something very specific, reach out to our team and we can help you find the right fit. Generally, an envelope should measure 0.25" larger than what is being inserted.

The right envelope size depends on what you’re sending, but a few sizes are used more often than others. #10 envelopes are a standard choice for everyday business mail. Invitation and announcement envelopes come in a range of sizes for cards, invitations and stationery, while booklet and catalog envelopes are designed for larger documents and materials. Our Envelope Size Guide can help you compare envelope dimensions and find the best fit for your project.

The #10 envelope is the most common business envelope. It measures 4 1/8" x 9 1/2" and is typically used for invoices, statements, checks, letters and everyday business mail.

There are a lot of options, and the best one really depends on what you’re sending.

You can also narrow your search by size, color, paper, closure style and other features.

For everyday business correspondence, #10 envelopes are one of the most common choices. Window envelopes are helpful when the recipient’s address is already printed on the document inside, such as an invoice or statement. Security envelopes provide additional privacy for sensitive contents. For larger documents that shouldn’t be folded, booklet or catalog envelopes may be a better fit.

The easiest way to tell them apart is by where they open. Booklet envelopes open along the long side, while catalog envelopes open along the short side. Booklet envelopes are a popular choice for brochures and marketing materials. Catalog envelopes work well for documents, reports and other larger pieces that you don’t want to fold.

Both are self-sealing options that do not require moisture, but they work differently. Simple Seal uses two adhesive surfaces that seal when pressed together. Peel & Seal uses a single adhesive strip protected by a removable liner. With Peel & Seal, you remove the liner and press the flap closed. Both are convenient choices for everyday mailing. The best option depends on the envelope style and how you prefer to seal your mailings.

For documents that can be folded, a standard business envelope may work well. For larger documents, presentations, reports or other materials that should remain flat, consider a booklet or catalog envelope. Check the envelope dimensions before ordering to make sure your materials will fit comfortably.

Window envelopes have a clear opening that allows an address or other information printed on the document inside to show through. They’re commonly used for invoices, statements, checks and other business mail. Non-window envelopes have a solid front and can be addressed by printing directly on the envelope, handwriting the address or applying a label.

Peel & Seal envelopes have a removable strip covering the adhesive. Peel it off, press the flap down and you’re done. Traditional gum closures need to be moistened before sealing.

If your design prints all the way to the edge of the available print area, it may need to extend into the bleed area. This helps prevent an unwanted white edge after production. The safety area is where important information such as your logo, text or address should stay so it isn’t too close to an edge or production area. Your product template will show you where these areas are.

Often, yes, but every printer is different. Envelope size, paper weight, finish and construction can all affect how an envelope feeds through a printer. Check your printer’s specifications first. For a larger project, we strongly recommend testing a sample before ordering a full quantity.

It could be the envelope thickness, size, feed direction or your printer settings. Some printers also have limits on the paper weights and envelope styles they can handle. Check your printer’s envelope or manual-fe

We do our best to represent colors accurately, but screens vary. A color can look different depending on your phone, monitor and display settings. If matching a specific color matters to your project, order a sample first.
