Picture Hanging Height Calculator: Where to Put the Nail

By the KDS London team Updated 2026 London interiors

Enter the frame size and how far the hook or wire sits below the top, and we'll tell you the exact height to mark for the nail. Hanging pictures too high is a common mistake. Galleries tend to put the centre of a picture at about 145 cm from the floor, roughly eye level for a standing adult, and that single number fixes most walls.

Where is the picture going?

Drop = distance from the top of the frame down to the hanging point. For a wire, pull it up taut towards the top as it will be on the nail, then measure. For a sawtooth or keyhole, measure to the notch.

145 cm suits most rooms. Try 135 to 140 cm in a dining room or snug where people mostly sit, or if your household is on the shorter side.

Measure to the top of the sofa back, headboard or sideboard. Keeping art close to the furniture makes the two read as one group.

How the calculation works

On an open wall, the bottom of the frame sits at the centre height minus half the frame height. Add the full frame height to get the top edge, then subtract the drop to find the hanging point. Above furniture, the bottom of the frame starts at the furniture height plus your chosen gap, and the same top-minus-drop step gives the nail.

Worked example: a 60 cm tall frame with an 8 cm wire drop, centred at 145 cm. The bottom edge is 145 minus 30, so 115 cm. The top edge is 175 cm. The nail goes at 175 minus 8, which is 167 cm from the floor.

Tips before you drill

  • Mark the nail point lightly in pencil, then hold the picture up once more before drilling. Painter's tape on the wall makes marks easy to remove.
  • For a gallery wall, treat the whole group as one big picture: use its overall height in the calculator, then arrange the frames inside that outline.
  • For a run of pictures in a row, keep the centres on one line rather than lining up the tops, unless the frames are all the same size.
  • Check the wall before fixing. Use a cable and pipe detector, and choose fixings rated for the weight and the wall type (solid masonry, plasterboard or lath and plaster).
