Gazebo Roof Rafter Calculator

Gazebo Roof Rafter Calculator is the essential tool for builders, carpenters, and DIY enthusiasts who need precise measurements for gazebo roof construction. 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. Set the number of sides, face width, hip angle, and cleat length, then generate a precise template diagram showing exactly how your bracket should look. Adjust the cleat length with an interactive slider and see results update in real time.
