How to Measure a Blind for a Window

Measuring a blind for your window might seem like a straightforward task, but it's crucial to get the dimensions right to ensure a perfect fit and optimal functionality. This guide will walk you through the process, from understanding the types of blinds to measuring them accurately.

Before we dive into the measuring process, let's briefly discuss the types of blinds you might have. The most common types are roller blinds, venetian blinds, and roman blinds. Each type has its unique features and measuring requirements, which we'll cover in detail.

Understanding Your Blind Type

Roller blinds are simple and elegant, consisting of a single piece of fabric that rolls up and down. Venetian blinds, on the other hand, have horizontal slats that can be tilted to control light and privacy. Roman blinds are made of fabric that folds neatly when raised.

Knowing your blind type is essential because it affects how you measure for a replacement or a new blind. For instance, roller blinds are measured differently from venetian blinds, which in turn have different measurements from roman blinds.

Measuring for Roller Blinds

Roller blinds are measured in two dimensions: width and drop. The width is the horizontal measurement from side to side, while the drop is the vertical measurement from the top of the blind to the bottom.

To measure the width, use a metal tape measure and extend it across the window frame from side to side. Make sure to measure to the widest point, as roller blinds are typically installed inside the window recess. For the drop, measure from the top of the window recess to where you want the blind to end. Remember to account for any obstructions like ledges or sills.

Measuring for Venetian Blinds

Venetian blinds are measured similarly to roller blinds, with width and drop measurements. However, you also need to consider the slat size. Slats typically come in 25mm, 35mm, 50mm, and 63mm widths.

When measuring the width, follow the same steps as for roller blinds. For the drop, measure from the top of the window recess to the bottom, but this time, you need to account for the slat size. If you want the blind to cover the entire window, subtract the slat size from the total drop. For example, if your drop is 900mm and you've chosen 50mm slats, your blind should be 850mm to allow for the slats at the top and bottom.

Measuring for Roman Blinds

Roman blinds are measured like roller blinds, with width and drop measurements. However, the drop measurement is a bit more complex due to the way roman blinds fold.

To measure the width, follow the same steps as before. For the drop, measure from the top of the window recess to where you want the blind to end. However, unlike roller or venetian blinds, roman blinds will fold when raised, so you need to account for this in your measurement. A good rule of thumb is to add an extra 100mm to 150mm to your drop measurement to allow for the folds.

Measuring for Headroom

Headroom refers to the space between the top of your blind and the ceiling. It's important to measure this space to ensure your blind has enough room to roll up or fold when raised.

Measure the space from the top of the window recess to the ceiling. This measurement will determine how high your blind can be raised. If you have a low ceiling or obstructions like light fixtures, you might need to adjust your blind type or size.

Once you've taken all these measurements, it's time to order your new blind. Always double-check your measurements to ensure accuracy. If you're unsure about any aspect of the measuring process, don't hesitate to contact a professional for advice. After all, a well-measured blind is a happy blind, providing years of trouble-free service and enhancing your home's aesthetic appeal.
