5×7" Print Guide
Everything you need to print 5x7" Photo sharp
The 5 × 7 inch print (13 × 18 cm) is the standard size for greeting cards, wedding invitations, announcements and small framed photos on a desk or shelf.
Its 5:7 shape is slightly squarer than a camera’s 3:2, so camera photos lose a little from the long side. At 300 DPI it needs 1500 × 2100 pixels, about 3.2 megapixels, well within any modern camera or phone.
Because cards and invitations are held and read up close, 300 DPI matters most for the text on them. Lettering looks best when it is kept as real text in a PDF rather than flattened into the image.

Tips for printing at 5×7"
- Designing an invitation? Most printers ask for 1/8 inch (3 mm) of bleed per side: 5.25 × 7.25 inches, or 1575 × 2175 pixels at 300 DPI.
- Two fit on a US Letter sheet (8.5 × 11 in), so you can print a pair at home and trim them.
- Folded cards printed flat at 10 × 7 inches fold to 5 × 7: design at 3000 × 2100 pixels for 300 DPI.
5×7" questions
How many pixels is a 5 × 7 at 300 DPI?
1500 × 2100 pixels. With 1/8 inch bleed on each side it is 1575 × 2175 pixels.
Will a 5 × 7 crop my photo?
A little. Camera photos are 2:3 and 5 × 7 is 5:7, so about 7% of the long side is trimmed. Phone photos (4:3) lose a little from the short side instead.
Which envelope fits a 5 × 7 card?
In the US, an A7 envelope (5.25 × 7.25 in). In Europe, C6 envelopes (114 × 162 mm) are too small; use a C5 or a 5 × 7 specific envelope.

Pixels = Inches × Target DPI
Example for 8×10" at 300 DPI: (8 × 300) = 2400 px width, (10 × 300) = 3000 px height.
Pixels = (Millimeters ÷ 25.4) × Target DPI
Example for A4 (210×297 mm) at 300 DPI: (210 ÷ 25.4 × 300) = 2480 px, (297 ÷ 25.4 × 300) = 3508 px.
