UNDERSTANDING THE IMPORTANCE OF ACCURATE MEASUREMENTS FOR CUSTOM BLINDS
Nothing derails the excitement of new blinds more than realizing they don’t fit. Too wide and they overlap messily, blocking trim and tilting awkwardly. Too narrow and unsightly slivers of light sneak through, betraying your privacy. The right measurements ensure your investment in custom blinds pays off with fit, function, and style. Whether you desire the luxurious drape of Roman shades, the crisp lines of roller blinds, or the timeless appeal of Venetian styles, the process always begins with precise dimensions.
According to Houzz’s expert guide, accurate measurements are essential because custom blinds are manufactured to your exact specs, leaving little to no room for error.

INSIDE MOUNT VS OUTSIDE MOUNT: WHICH IS BEST FOR YOUR SPACE?
Before picking up your measuring tape, decide on an inside or outside mount. This crucial choice shapes the look, function, and even energy efficiency of your new window treatments.
- Inside Mount: The blind sits within the window frame, creating a sleek, tailored appearance. This is ideal for deep window frames and a modern look. It also lets you show off beautiful trim work.
- Outside Mount: The blind or shade covers the window and frame entirely, making windows appear larger and hiding unattractive casings. It’s optimal for shallow frames or if you want to block out more light.
Each method has its advantages. For rooms requiring maximum privacy or light control, outside mount often edges ahead. For a clean, architectural effect, inside mount is the go-to. Better Homes & Gardens points out that your choice should factor in window depth, obstructions, and your design vision.
STEP-BY-STEP PROCESS: HOW TO MEASURE FOR CUSTOM BLINDS
Let’s embark on the measurement journey with precision. You’ll need a steel measuring tape, notepad, and a pencil. Always measure to the nearest 1/8 inch for accuracy. For each window, measure the width and height in three places: top, middle, and bottom. Record the narrowest width and the tallest height, as this ensures a perfect fit.
- Width Measurement (Inside Mount): Measure the inside width at top, middle, and bottom. Write down the narrowest width. This avoids blinds that won’t fit into the frame.
- Height Measurement (Inside Mount): Measure from the top inside edge to the sill at left, center, and right. Use the longest height to ensure full coverage.
- Depth: Check your window’s depth (from glass to edge of frame). Some blinds need a minimum depth to mount properly.
- Width Measurement (Outside Mount): Measure the width you want covered. Add at least 2-3 inches to each side for optimal privacy and light blocking.
- Height Measurement (Outside Mount): Measure from where you want the headrail placed to where the blind should end. Add extra height for complete coverage.
Always double-check your numbers. If you’re measuring multiple windows that appear the same, measure each individually. Variations—even a quarter inch—can matter when it comes to fit.
TOOLS AND TIPS FOR MEASURING LIKE A PRO
A steel measuring tape provides the most reliable results. Avoid cloth tapes as they can stretch and cause inaccuracies. Keeping your tape straight and level is essential for consistent results. Write down each measurement immediately to avoid confusion later. Mark each window and clearly label every dimension for easy reference when ordering.

COMMON MISTAKES AND HOW TO AVOID THEM
Many homeowners make small yet critical errors. Measuring only once, rounding up measurements, or assuming all windows are identical can lead to disaster. Additionally, ignoring hardware placement, window handles, or trim can result in blinds that don’t hang or function as intended. Always choose accuracy over guesswork.
As The Spruce highlights, it’s important not to subtract from your width measurement for inside mounts—manufacturers make the necessary deductions so your blinds fit perfectly.
Additionally, factor in child safety. If you’re installing blinds in a child’s room, consider cordless or wand-operation for added peace of mind, as recommended by industry experts (The Spruce, 2023).
