## Ways to Take Window Measurements for Different Curtain Styles

Do you want to buy curtains for your new home or want to get a new look for the old one? Then you need to collect the correct measurements. The standard units used for taking curtain measurements are inches or centimetres.

For long curtains, we take measurements from the top of the window frame to the point where you want the curtain to stop. For short curtains, we follow this:

• From the window top to the top of the sill for sill-length curtains.
• From the window top to the bottom line of the apron, for apron length curtains.

### Standard Curtain Size Formulas

The standard curtain sizes for long curtains are 72 in, 84 in, 96b in, and 108 in, for short curtains are 24 and 36 inches.

The formulas to find the curtain size for sill, apron, and floor length curtains are here:

• Curtain Length = Height + Height of rod
• For cafe length curtain length = Height/2
• For extra long curtains curtain length = Height + Height of rod + 6

The standard curtain width is always 2, 2.5 or 3 times the width of the window.

The formulas used to calculate the curtain width are:

• Standard curtain width = window width x 2
• Deluxe curtain width = window width x 2.5
• Utla fullness curtain width = window width x 3

### How to Calculate Curtain Length and Width?

The steps to compute the curtain size are outlined here:

• Get the window height and width either in inches or cms.
• Know the type of curtain you want to buy and curtain fullness.
• Place the values in curtain length and width formulas to obtain the answer.

When you choose the standard height, add 4 inches to the original size to accommodate your rod's placement. For a room with a high ceiling, adding 6 inches is better. When you are going to buy an exceptionally long style curtain, then add another 6 inches.
