Flyer and poster sizes in the US

US paper sizes are not tied to the metric A series. The file is generated at 300 dpi, the resolution print shops expect.

Margins, bleed and crop marks

Most home printers leave about 0.2 in of blank border. A print shop trims the sheet after printing, so keep text at least 0.24 in (6 mm) from the edge, the white guide in the preview. If you check crop marks, the PDF adds a 0.4 in margin with corner marks. For full-bleed jobs at a print shop, ask for their exact bleed specs.

Build a flyer people actually read

  • One main message: the headline, set very large.
  • When and where before anything else: the date and place should be readable from six feet away.
  • A photo or an icon to catch the eye, and never more than three fonts.
  • A clear call to action: a phone number, email or website at the bottom.

To send people to a website, make a code with our custom QR code generator, then add it to the flyer as an image.

Frequently asked questions

What size is a standard flyer?
The most common are US letter (8.5 × 11 in) and half letter (5.5 × 8.5 in). A 4 × 6 in postcard-style flyer is also popular for handouts.
What resolution do I need to print a poster?
300 dpi, which means 300 pixels per inch. The downloaded file has that resolution: 2550 × 3300 pixels for a letter page.
How do I print my flyer at home?
Open the PDF, choose “Actual size” or 100% in the print dialog, and turn off “fit to page” so the dimensions stay exact.
Can I add my own photo?
Yes, from your device. It stays in your browser while you design. Use a photo at least 1500 pixels wide so it stays sharp on letter paper.
What are crop marks for?
They show you or your print shop where to cut the sheet. They sit in a 0.4 in margin around your design.
