GarageDoorTo calculation methodology
The service uses transparent geometry and editable planning profiles. It does not present one universal clearance as correct for every product.
Core formulas
- Finished width = smallest rough width − left finish − right finish.
- Finished height = smallest rough height − top finish − floor build-up.
- Slope level difference = length × slope percentage / 100.
- Drive-through clearance = finished opening − editable frame and fascia losses.
Planning profiles
Defaults are conservative starting points and not manufacturer approvals. Enter exact dimensions from the chosen technical card.
