Outer or inner corner for your railing

When ordering a railing from us, we need to know whether the corners are outer or inner corners.

Why do we want to know the corner type?

We need to know because in some cases, we need to add or subtract from the sides depending on the corner type. This enables us to correctly calculate the dimensions of each part so the final delivery meets your requirements.

We are aware that it can be a bit tricky to grasp what is an inner and an outer corner, so we would give some examples to help.

Study the inside of a railing

When we are talking about the corners, we always see them from the “inside” of the railing. Imagine that you are standing on the side that the railing will frame. If it is a terrace or balcony, you need to imagine you are standing on it. An outer corner thus “points” outwards, while an inner corner “points” inwards.

The image above illustrates a staircase that should have a railing at the sides of the stair opening. Side 1 ends at the wall and side 3 ends where the stairs descend.

In this case, side 1-2 is an inner corner and side 2-3 is an outer corner.

Corners that are not 90 degrees

Even if the corners are not 90 degrees, they still count as outside or inside corners.

Above is image from our measurement templates where we illustrate inner and outer corners for examples that are not 90 degrees.
