What size should an invitation be for WhatsApp?
WhatsApp has no official size and compresses images, so print sizes and dpi don't matter on a phone. What matters is the shape and enough pixels for text to stay sharp: a portrait image 1080 pixels wide works well, and large text survives the compression better.
| Where | Shape | Pixels |
|---|---|---|
| WhatsApp chat | 4:5 portrait | 1080×1350 |
| WhatsApp Status | 9:16 full screen | 1080×1920 |

How are the pixels worked out?
Pixels are the print size in inches multiplied by the resolution in dots per inch. Millimetres are divided by 25.4 first. A 5×7 inch card at 300 dpi is 5 × 300 by 7 × 300, so 1,500 × 2,100 pixels. Bleed is added to every side before multiplying.

Questions about invitation sizes
How many pixels is a 5×7 invitation?
At 300 dpi, the usual resolution for printing, a 5×7 inch invitation is 1,500 × 2,100 pixels. With ⅛ inch of bleed on each side for edge-to-edge printing, the file is 1,575 × 2,175 pixels.
What resolution should an invitation be for printing?
300 dpi, which is what print shops expect for sharp text and fine lines. 150 dpi is enough for a quick draft on a home printer, but small text can look soft.
What is bleed on an invitation?
Bleed is extra background beyond the edge of the card, usually ⅛ inch or 3 mm on each side. The printer trims it off, so colours and pictures run right to the edge without a thin white line. Keep text a little way in from the edge too.
