The size of a standard door hanger can vary slightly depending on the design and the specific purpose it serves, but there are common dimensions that are widely used in the industry.

The most typical sizes for door hangers are…

• 3.5 x 8.5 inches (88.9 mm x 215.9 mm) – This is a very common size for door hangers, offering enough space for information and graphics without being too large. It’s compact and cost-effective for printing while still being noticeable.
• 4.25 x 11 inches (107.95 mm x 279.4 mm) – This larger size provides more space for detailed information, larger graphics, or additional offers. It’s particularly useful for campaigns that require more content to effectively convey the message.

These dimensions include a cut-out hole or slit at the top, which allows the door hanger to hang on doorknob handles easily. The hole is typically designed to fit most standard doorknobs, ensuring that the door hanger can be used in a wide range of locations.

The choice between these sizes (or other variations) depends on the specific needs of the campaign, including the amount of information to be displayed, the target audience, and budget considerations. The larger size might be more appropriate for detailed marketing campaigns or when you want to make a bigger visual impact, while the smaller size can be a cost-effective choice for simpler messages or tighter budgets.
