Measuring your windows may seem tricky, but it’s easy if you take it step by step. If you’ve been wondering how to measure for window shades and blinds, this guide is made just for you. Taking the right measurements helps you get a perfect fit for your home. Whether you’re choosing roller shades, faux wood blinds, or vertical blinds, this guide will help you feel confident. At Blinds Crafter, we make sure our customers know exactly how to measure before they order.
Let’s start with why measuring matters.
Why Measuring Matters Before You Order Window Coverings
Getting the measurements right means your window treatments will look better, work better, and last longer. If blinds are too short, they let in too much light. If they’re too wide, they won’t fit inside the window frame. Proper blind measurements also help avoid gaps that let in light or take away from privacy.
When you measure the right way, you can order with peace of mind. No guessing, no mistakes. Just the right size for a clean, professional look.
Understanding the Different Types of Window Treatments
There are many window treatments to choose from. You might like roller shades for a modern look or prefer roman shades for a softer style. Blinds come in many styles, too, like faux wood, vertical, and mini blinds. Each one has its benefits.
Some fit inside the window frame, while others are mounted outside of it. These are called inside mount and outside mount options. Understanding these types will help you choose the right design for your space.
What You Need Before Measuring: Tools and Setup
Before you begin measuring, make sure you have these things ready:
- A metal tape measure (not a fabric one)
- A pen or pencil
- A paper or a notebook to write down the numbers
- A step stool if your windows are high
- A clear view of the full window frame
You’ll also want to know if you’re measuring for blinds or shades. Roller shades, vertical blinds, or cellular shades each need accurate width and height numbers. Always write your width first, then height.
Inside Mount vs. Outside Mount: Choosing the Right Fit
When you measure, you first need to decide between inside mount blinds or outside-mounted blinds. This choice affects how your window coverings will look and how they will function.
Inside mount means the shade or blind fits within the window frame. It gives a clean, built-in look and works best if the window has enough depth. Outside mount is when the blinds or shades go over the frame. This is better if the window has shallow depth, or you want to block more light.
A good tip: measure the depth of your window. If it’s less than 2 inches, an outside mount might be the best option.
How to Measure for Inside Mount Window Shades and Blinds
To measure for inside mount window blinds:
-
Width
Measure inside the window opening at the top, middle, and bottom. Write down the smallest number. That’s your final width.
-
Height
Measure the left, middle, and right sides from top to bottom. Use the longest height.
-
Depth
Measure from the window frame to the glass. This tells you if your window has enough space for inside mount blinds.
Write your numbers carefully and round down to the nearest 1/8 inch. This avoids fit issues. You don’t need to subtract anything; blind companies do that for a perfect fit.
Measuring for Outside Mount Blinds: A Simple Approach
Outside mount blinds cover more area and can make windows look larger. They also help block more light. Here’s how to measure:
-
Width
Measure the width of the window frame and add 3 to 4 inches on each side. This gives you overlap for better light control.
-
Height
Measure from the top of where you want the blind to start (above the frame) down to where you want it to stop, usually below the window sill.
This method gives full coverage. Be sure to check for any obstacles like molding or trim that may affect the mounting brackets.
Pro Tips for Measuring Roller Shades, Vertical Blinds & More
Different window coverings need slightly different measurements. Here are some pro tips:
- Roller shades: If you’re measuring inside mount, be sure to measure the depth of these shades to ensure they have enough space to roll up.
- Vertical blinds: These are great for sliding glass doors. For width, measure the full opening and add a few inches for overlap. For height, measure from the top of the frame to the floor.
- Roman shades: These stack in folds when raised. Make sure the top of the window has room for that stack.
Always double-check your measurements. If you’re unsure, take a second reading or ask a design consultant.
Avoid These Common Mistakes When Measuring for Blinds
Even small mistakes can lead to a poor fit. Here’s what to watch out for:
- Measuring the frame instead of the inside opening
- Forgetting to measure depth for inside mount blinds
- Rounding up instead of rounding down
- Not checking if the windows are level.
Also, avoid switching width and height. Always writewithh first. Use a metal tape measure and hold it straight. A bent tape can throw off your numbers.
How to Measure for Window Shades and Blinds in Saddle River, NJ Homes
Homes in Saddle River, NJ often have custom-sized or older window frames. That means careful measuring is extra important. Look for signs of uneven frames or window sills that aren’t level.
If your home has wood trim, measure from edge to edge for outside mounts. For inside mounts, check that there’s enough depth, especially in older homes with narrow frames. At Blinds Crafter, we often help customers in this area take the guesswork out of measuring.
What to Do If You’re Measuring for Sliding Glass Doors or Large Windows
Large windows and glass doors need special attention. For vertical blinds, measure the full width of the opening and add extra for overlap. For height, measure from the top edge to the floor, then subtract half an inch for clearance.
Faux wood blinds or cellular shades can also work for wide openings, but make sure your brackets can support the weight. You may need multiple blinds on one headrail. Measure each section carefully and label your notes.
Custom Window Treatments Start with Perfect Measurements
Custom blinds and shades are made to fit your exact window size. That’s why the measurements you take are so important. Unlike pre-cut blinds, custom options don’t leave large gaps or need trimming. They come ready to install.
When measuring for custom window coverings, always take your time. Write down every number, double-check your notes, and make sure you understand whether you’re ordering for inside mount or outside mount. If you’re ever unsure, reach out for help or use professional measuring services.
Choosing the right product starts with the right size. Whether it’s wood blinds, fabric shades, or roller blinds, every type needs accurate width, height, and depth to look and function at its best.
