Whether you're a professional framer or building your first backyard gazebo, this app delivers accurate calculations in seconds — no more manual math or guesswork on the job site. GAZEBO GEOMETRY CALCULATOR Enter your gazebo parameters — number of sides, rafter dimensions, roof angle, eave overhang, and birdsmouth seat — and instantly get every measurement you need: - Floor area, side lengths, and triangle section dimensions - Hip rafter angle, total length, and plumb cut angles - Centre rafter length and side cut angles - Creeper (jack) rafter lengths with plumb and side cuts - Nogging centres, plumb angles, and side angles - King post radius, face width, and bounding rectangle - Roof segment dimensions, inner/outer angles, and bevel angles - Total roof area and material quantities - Batten spacing with miter and bevel cut angles Every calculation comes with detailed interactive diagrams — floor plan, roof profile, hip rafter, centre rafter, creepers, king post, and roof segments — all drawn to scale so you can visualize the build before cutting a single piece of timber. CENTRE BRACKET TEMPLATE GENERATOR Design the perfect centre bracket for your gazebo peak.
