How to Measure for a Picture Frame or Wall Art

Wall space, art height (relative to furniture), and the rule of two-thirds for centered placement.

Hanging art looks intentional when it follows three rules: centered horizontally on the wall, eye level vertically (when standing), and 2/3 the width of the furniture beneath. iPhone makes verifying these instant.

Why measure this

  • Center art on the wall (or above furniture)
  • Hang at correct eye-level height (~145-155 cm to center)
  • Match scale to furniture (2/3 rule)
  • Plan multi-piece gallery walls

What you need

  • iPhone with Ruler AR
  • Length and Height modes
  • Bubble level for hanging

Step by step

  1. Wall width. Tap left edge of wall to right edge.
  2. Furniture width (if hanging above). Sofa, console, bed width. Art should be 2/3 of this.
  3. Eye level marker. Use Height mode. Mark 145-155 cm on the wall (varies with viewer height). Center of frame goes here.
  4. Frame center to top. On the frame: tap from center to top edge. This tells you how high to drive the nail (eye-level + half height + ~2 cm hanging wire).

Tips

  • For gallery walls: leave 5-10 cm gap between frames
  • Above sofa: leave 15-25 cm gap between art bottom and sofa top

Common mistakes

  • Hanging too high, art floats far above furniture
  • Center misalignment by even 2-3 cm reads wrong
