Print sizes
The trim size is the finished card, after cutting. Everything on this site is set up at one of these sizes, with bleed and safe margins already configured.
| Size | Inches | Millimetres | Pixels at 300 DPI | Envelope |
|---|---|---|---|---|
| 5 × 7 in | 5 × 7 in | 127 × 178 mm | 1500 × 2100 | A7 (5.25 × 7.25 in) |
| 4 × 6 in | 4 × 6 in | 102 × 152 mm | 1200 × 1800 | A6 (4.75 × 6.5 in) |
| 5 × 5 in | 5 × 5 in | 127 × 127 mm | 1500 × 1500 | Square 5.5 × 5.5 in |
| A6 (105 × 148 mm) | 4.13 × 5.83 in | 105 × 148 mm | 1240 × 1748 | C6 (114 × 162 mm) |
| A5 (148 × 210 mm) | 5.83 × 8.27 in | 148 × 210 mm | 1748 × 2480 | C5 (162 × 229 mm) |
Digital sizes
For sharing rather than printing. These are measured in pixels because they are never cut, so bleed does not apply.
| Size | Pixels | Best for |
|---|---|---|
| Digital | 1080 × 1350 | For sharing on WhatsApp, email, and social feeds. |
| Story | 1080 × 1920 | Full-screen vertical format for stories and status updates. |
| Square | 1080 × 1080 | Square image for feeds and group chats. |
What bleed is, and why it matters
Printing presses and guillotines are accurate to about a millimetre, not to zero. If a background colour stops exactly at the edge of the card, a cut that lands a hair outside leaves a thin white sliver down one side.
Bleed solves this by extending the background past the cut line, so there is spare artwork to trim into. The standard is 0.125 inches (about 3 mm) on each side. A 5 × 7 card with bleed is designed at 5.25 × 7.25 inches and cut back down to 5 × 7.
The mirror of bleed is the safe margin: keep anything you need people to read at least a quarter inch inside the cut line. Text that sits closer than that can end up looking off-centre even when the cut is technically fine.
How many pixels do I need?
For print, 300 DPI is the number to aim for. Multiply the size in inches by 300: a 5 × 7 card needs 1500 × 2100 pixels for the trimmed area, or 1575 × 2175 including bleed.
This matters most for photographs. A picture that looks sharp on a phone screen can be well under 300 DPI once it is scaled up to fill an invitation. Our editor works out the effective resolution of every image you place and flags the ones that will print soft, before you download rather than after you have paid for a hundred cards.
Which size should I choose?
- 5 × 7 in is the default for weddings and anything formal. It has room for full wording without crowding, and A7 envelopes are easy to find.
- 4 × 6 in is cheaper to print and to post, and is a good fit for a birthday or a casual party where the wording is short.
- A6 is the European equivalent of 4 × 6 and pairs with C6 envelopes.
- Square 5 × 5 in looks distinctive but needs square envelopes, which usually cost more to post. Check with your postal service before committing.
