About

Staircase3D: Stair Calculator Plan your staircase with stair stringer calculation, tread depth, riser height and landing dimensions. Calculate stringer geometry and inspect your staircase design in 3D. Measure from finished floor to finished floor. Draw from the bottom of the staircase to the top. Two nodes per level are free; three or more require paid editing access. Use 3D to inspect the stair and Save to commit the whole project. Recovery drafts are separate from saved projects. Always verify dimensions, construction and local requirements with a qualified professional. Projects with up to two nodes per level are free. Keep unlimited projects. Saved 3D views, drawings, notes and exports remain available after your subscription ends. Unlock editing for projects with three or more nodes on any level. Eligible subscribers get the first month free, then pay the regular monthly price. Cancel before the trial ends to avoid being charged. Renews automatically at the regular monthly price until cancelled in your Apple subscription settings. Permanent editing access for all your projects. No recurring charge. A lifetime purchase does not cancel your current subscription. Manage it with Apple to avoid further subscription charges.
