How to make an envelope from a template
- Print the template — or print it on plain paper and trace it onto patterned paper, wrapping paper or a magazine page.
- Cut around the outline and score the four fold lines.
- Fold in the side flaps, glue the bottom flap over them and let it dry.
- Slide the card in and seal the top flap with glue, double-sided tape or a sticker.
About the Envelope Template Generator
📏 Fits your card
Enter the card size and the envelope gets just enough room for the card to slide in — or type the finished envelope size if you're matching a standard one.
✉️ Two classic folds
The classic style has side flaps and a glued bottom pocket like a shop-bought envelope. The diamond style folds four pointed flaps in from a single sheet.
💌 Five flap shapes
Pointed, straight, rounded, wallet or scalloped — and an optional liner template cut to fit inside the flap for a patterned-paper finish.
🪟 Address window
Add a window in the standard place for DL and #10 business envelopes, so a folded letter's address shows through.
🖨️ Any paper
Prints on A4, Letter, A3 or 12 × 12 inch scrapbook paper. Bigger envelopes split across pages with alignment marks.
✂️ Cutting machines
Download an SVG with cut and score lines on separate layers, in real millimetres, for Cricut, Silhouette or a laser cutter.
Frequently Asked Questions
What size envelope do I need for a 5 x 7 card?
A 5 × 7 inch card fits an A7 envelope, which is 5¼ × 7¼ inches. Pick "5 × 7 card (A7)" from the list and the template is sized for you.
How much bigger than the card should an envelope be?
About 3 mm (⅛ inch) on each side is the usual allowance — enough for the card to slide in without rattling. In "Card size" mode the tool adds this for you.
What paper is best for envelopes?
Paper around 90–120 gsm (24–32 lb) folds crisply and is strong enough to post. Thicker card is fine for hand-delivered envelopes. Wrapping paper and magazine pages make fun envelopes too — trace the template on the back.
Can I post a homemade envelope?
Usually yes, as long as it is sealed well, the address is clearly readable and it meets your postal service's size and thickness rules. Square or unusually shaped envelopes may cost extra postage.
What is an envelope liner?
A liner is a sheet of decorative paper glued inside the envelope so the pattern shows when the flap opens. The liner template is cut slightly smaller than the flap and folds along the same line.
What size envelope fits an A6 card?
A C6 envelope (114 × 162 mm) fits an A6 card (105 × 148 mm). In US sizes, an A6 envelope (4¾ × 6½ in) fits a 4½ × 6¼ in card.
What size is a DL envelope?
DL is 110 × 220 mm and holds an A4 sheet folded in three — the standard business letter envelope outside North America.
