How to measure for curtains?

This guide has been specially created to help you develop the rod size and how to measure for curtains.

Calculate the Width

The development of the exact width is essential to have a blind proportioned correctly to the size of the window.

The curtain must generally cover the window at least 10 cm. to the right and the same number to the left. If there is a frame of the window or the box, the centimetres must be calculated over.

For example, the window has a size of 120 cm. The final width will be 140 cm.

Difference between stick and rail

If you have to mount a stick, The width we have calculated will be that of the positioning of the supports. The pipe must protrude at least another 5 cm. per part (terminals excluded). Example window cm.120 measure of the stick must be cm.150 minimum.

Suppose you have to mount a track with sliding doors. In that case, The minimum size we have calculated is also good as the finished size of the path, which, not having the obstacle of the supports (which usually are mounted in the upper channel), will allow the awning to slide along its entire length.


It is also essential to calculate the right protrusion of the rod and curtain for the wall for a right sliding of the curtain.

Using the measuring tape, starting from the wall, overcome any obstruction (e.g. box, handle, window sill, etc.) and add an average of 5 cm—the size of the curtain that has been chosen changes a lot. For example, for the wave curtain, it will be necessary to calculate a sliding space of at least 10 cm because the waves clutter in front and behind the rod to measure for curtains.

Buy a stick mounted on the ceiling. It will make it possible to calculate the protrusion even at the time of assembly. Instead, you believe a rod mounted on the wall, it is necessary to calculate the lump to understand if the size of the supports is adequate for the need.

Calculate the Height

The height calculation only concerns the curtain and not the rod. The exact total is uniquely related to the type of rod or rail. We have to mount and whether the mounting will be done on the ceiling or the wall.

The first rule is to calculate starting from the floor and not from the ceiling. 

If ceiling mounting: Place the measuring tape from the ceiling to the floor and measure left. Right and centre to make sure the height is the same and there are no discrepancies. To calculate the height of the curtain, it will be necessary to reduce the size of the system. (Whatever it is) and about 1.5 cm, which will be the space between the curtain and the floor. 

Suppose you have to mount it on the wall. Generally, the stick position. Halfway between the window. And the ceiling (it is not an actual rule as it can position. Higher or lower depending on the needs). Place the tape measure at the height where you want to place it. The system measures for curtains by measuring down to the ground (do not calculate from the ceiling). For the height of the curtain. It will be necessary to reduce the size of the system (whatever it is). And about 1.5 cm, which will be the space between the curtain and the floor.

Half-height to measure for curtains

Suppose it is a window and not a balcony. It may be necessary to install a half-height curtain. That, therefore, does not reach the ground. Because the same precautions apply to take the measurement, in this case, a general rule is to cover the window at least 10 cm. At the bottom, unless there are obstacles and encumbrances.
