About

Ladder Angle Calculator

Features
Read full description

Set every ladder at the safe angle before you climb. LadderAngle finds the correct 4:1 lean (about 75.5°) from your wall height and ladder length, then lets you check the real angle live with your phone. Most ladder falls come from one thing: the wrong angle. Too steep and it tips back, too shallow and the feet slide out. LadderAngle turns the OSHA / HSE 1-in-4 rule into a two-second check — do the math first, then lean your phone on the rail and watch the on-screen angle turn green when it's right. WHAT YOU GET - The exact safe angle and base distance for your ladder, in metric or imperial - A clear SAFE / CAUTION / UNSAFE verdict as you type, so you never guess - A live inclinometer that reads the real ladder angle and locks the reading - A visual ladder diagram that updates as you change height, base or length - Saved setups for every ladder and job you check regularly - A built-in safe-setup checklist, 3-points-of-contact and duty-rating reference PERFECT FOR - Roofers and gutter cleaners setting extension ladders - Painters and decorators working off a lean-to ladder - Trade and construction crews who need an OSHA / HSE angle check - Home DIYers who want to climb without taking a chance WHY NOT JUST EYEBALL IT Guessing is exactly how ladders slide out. The 4:1 rule looks simple, but the base distance changes with every wall height — LadderAngle does that math instantly and then proves it against the real angle with your phone's motion sensor. No tape measure, no protractor, no maths in your head. PRIVACY Fully offline. No account, no ads, no tracking, no data leaves your phone. FULL ACCESS LadderAngle Pro unlocks the full app — the live inclinometer, unlimited saved setups, the complete safe-setup checklist and the OSHA / HSE / ANSI duty-rating reference.
