How to Measure Inside Mount Blinds

For inside mount blinds, that snug fit within your window casing is everything! Here's how you get it:


1. Start with the width

Measure across the top, middle, and bottom inside edges of the casing. Jot down the smallest of these measurements - that's your golden number!

2. Now onto the height

Measure along the left, center, and right side from the inside top edge down to the window sill. Your tallest measurement is the one you'll use. 

3. Precision is Key

Remember, inside mount measurements have to be precise. If your numbers are falling between the lines, round down to the nearest 1/8 inch.


Tools Required for Measuring Blinds

Grab your steel tape measure, pencil, and notepad, this handy trio is all you need to measure blinds and shades.


How to Measure Outside Mount Blinds

Outside mount blinds hang out - literally! They're installed outside the window casing and offer better coverage. Here's how to size them up:


1. Decide how much width the blinds will cover

Ideally, this should extend beyond the window edges by at least 2-3 inches on each side to help control light and ensure privacy.

2. Start at the top

For the height, start from where you'll place the top of the blind (include the headrail in your calculation) and measure down to where you'd like the blind to end. 

Hint: for windows without a sill, it's best to add 2-3 inches to your measurement for optimal coverage.

3. Round up

When it comes to outside mounts, if you're caught between two numbers, it's always better to round up.


How to Measure Blinds for Different Rooms

Now that you've mastered measuring inside and outside mounts, let's take a house tour, room by room.

Blinds for Bedrooms

When it comes to your private retreat, accuracy matters! Here's how to measure blinds for bedrooms:

1. With your trusty tape measure, capture the width and height of your window, recording the tiniest width and the longest height.

2. For inside-mounted blinds, remember to round down to the nearest 1/8 inch for a cozy fit. If it's outside-mounted blinds you're after, round up for extra coverage.


Blinds for  Living Rooms

Living rooms tend to have larger windows and, of course, larger blinds. Here's how to do it:

1. Whip out that tape measure again and record the width and height of the window.

2. Tip: for larger living room windows, outside-mounted blinds often do the trick.


Blinds for Kitchens

Kitchen blinds need to handle sunlight and splatters alike. Here's the scoop:

1. As with bedrooms and living rooms, jot down the width and height of your window.

2. Inside or outside-mounted blinds? It depends on the window’s location and size, and don't forget to round your measurements just right.
