WallHang

One line

WallHang turns a gallery wall from guesswork into a measured plan, with the exact nail position for every frame.

Short

Hanging a gallery wall is a measuring problem disguised as a design problem. WallHang solves the measuring part. Enter your wall size, add the frames you already own, try a linear, gallery or salon layout, and WallHang tells you where each nail goes, measured from the floor and the wall's left edge. It accounts for single hooks, picture wire and pairs of D-rings, so the frame hangs where you planned it.

Long

Most gallery walls start with paper templates taped to the wall, or a lot of extra holes. WallHang, a new iPhone app from Morrowfield Labs, replaces both with a measured plan.

You enter your wall's size in centimeters or inches and add up to 20 frames by their real outside dimensions, or pick a common size like 8×10, A4 or 50×70 cm. Start from a linear, gallery or salon layout, then drag, snap and space the frames on a canvas drawn to scale. When it looks right, WallHang switches to a hanging guide that shows the support point for every frame, measured from the floor and from the wall's left edge, so all you need is a tape measure and a level.

The math covers the part that usually goes wrong: hangers. WallHang knows that picture wire drops when pulled taut and that two D-rings need two level nails, and it calculates where each one lands on the wall. You can preview the arrangement on a photo of your own wall, save or share the preview, and export a printable PDF measurement sheet.

WallHang has no account, no ads and no tracking; everything stays on the iPhone. It's free for one wall with up to four frames. WallHang Pro is a one-time $7.99 purchase that unlocks unlimited walls, 20 frames per wall, PDF export and an AR preview on supported iPhones.
