Standard Sizes of Windows

In a building, the top of the doors and windows are placed at the same level. Thus the height of a window depends on the height where the window sill has to be fixed based on the circulation needed inside the building. Width of windows depends on the opening required.

The 10 WT 12 designation represents a double shutter window of 1000 mm (= 10 × 100) width and 1200 mm (= 12 × 100) height. Table 20.2 shows the Indian Standard Windows.
