Wall Art Size Calculator

Find the perfect size for your wall art or mirror using classic interior design principles.

Where will it hang?

Enter the space you’re working with to get a suggested width. For a piece above furniture, use the furniture width instead of the entire wall.

Why Use a Wall Art Size Calculator?

Choosing the right size for your wall art or mirror is crucial in creating a balanced and visually appealing space. Our calculator uses two classic interior design rules:

  • The 2/3 rule: Your art should be about two-thirds the width of the furniture it hangs over.
  • The 3/4 rule: For a bolder statement, aim for three-quarters of the furniture width.

By following these guidelines, you can create a cohesive look that ties your room together and makes a strong visual impact.

How to Use This Tool

  1. Choose blank-wall or above-furniture placement, then enter its width and the available artwork height.
  2. Click the "Calculate artwork size" button.
  3. Review the recommended sizes based on the 2/3 and 3/4 rules.
  4. Use these measurements as a guide when shopping for or creating wall art.

Arrange multiple frames visually

Use the Picture Wall Layout Generator to drag, drop, and try different frame sizes and arrangements before hanging.

Keep planning.
