Door sizing involves more than one measurement. The rough opening, frame dimensions, slab size, and clearance allowances all interact, and a mistake at any stage can cause installation problems.

Most french door projects begin with a picture in your head: a wide opening at the back of the house, both panels swung open on a summer evening, and far more daylight in a room that currently gets very little. It is one of the few changes that alters how a whole floor feels, which is why homeowners plan it long before they call anyone.
A front door is the first thing a guest notices and the last thing you touch when leaving home. In modern home design, it has shifted from a purely functional element to a key piece of the exterior, a place where the homeowner's design choices are most visible from the street, and where security, energy efficiency, and curb appeal all meet.
The short answer is this: Sliding doors save more interior space in most homes. A sliding door moves along a track and stays within its own frame line, meaning it never takes up floor area when opening or closing. A hinged door, by contrast, needs a clear swing arc that can reach up to 1.2 metres, depending on the door size.
Your front door does more than open and close. It's the first thing a visitor sees, the first line of defence against Toronto's freeze-thaw winters, and one of the few exterior upgrades that genuinely change how a home feels inside and out.
