How do I choose the right door hanger size?

Start by counting the elements your design actually needs, then let that number pick the size. Headline, image, offer, contact details, and a QR code all take space, and once you pass a handful of items the compact format gets crowded fast.

• Four elements or fewer: the 3.5 x 8.5 inch size stays clean and readable.
• Five or more, or photos and testimonials: step up to 4.25 x 11 inches for breathing room.
• Budget: smaller hangers cost less per unit on large runs, which matters at neighborhood scale.
• Readability: leave enough white space that the offer is legible at a glance on a doorknob.

When you are between sizes, favor the smaller one if the message is simple. Crowding a big idea onto a small card hurts more than a little extra size costs.
