WallMark Planner

WallMark Planner is a small, local-first picture hanging calculator for frames, art rows, and compact gallery walls. Enter your wall width, frame size, spacing, row or grid count, and hanger style. WallMark shows a clean preview and a simple list of nail marks so you can measure before hammering or drilling. WallMark helps you: - Plan one-row frame layouts. - Plan simple gallery wall grids. - Calculate center-hook, two-hook, and wire-drop nail marks. - Switch between inches and centimeters. - Save recent layouts locally on your device. - Check warnings when frames do not fit the wall space. WallMark is a planning aid for layout math. It does not detect studs, judge wall material, select anchors, or guarantee installation safety. You are responsible for choosing appropriate hardware and installation methods for your wall. No account. No ads. No tracking. No subscription.
