What is meant by Aspect Ratio?
The aspect ratio of of any item is the proportional relationship between its width and its height. It is commonly expressed as two numbers
separated by a colon, as in 16:9. In case of windows it purely depends on the window sizes which are given by the architects/ designers/ specifiers. A Fabricator can always refer to the max & min size limitations given by AIS in the guidelines. It plays a major role in the structural stability & functioning of the windows. For e.g. in casement system the recommended aspect ratio is 1:1.5. Whereas in Sliding Height to Width Ratio should be less than 1:2.5
