Inside mount blinds look built-in and clean, but they punish a sloppy measurement more than any other window treatment. The blind sits inside the frame, so a width off by a quarter inch either binds against the casing or leaves a light gap you can’t hide. The whole job comes down to measuring the opening at three points and trusting the factory to take the clearance. Before you start, it helps to know how to clean window blinds and how to clean venetian blinds for upkeep, curtain blinds if you plan to layer fabric, and how to measure a tv and how to measure for a sofa use the same measure-the-space discipline.
Is Your Window Deep Enough for an Inside Mount?
Check the frame depth first, because inside mount needs a minimum flat depth to hold the headrail. Most mini and faux-wood blinds want at least 2 inches of unobstructed depth for a flush mount, though some fit in less with a partial recess. Measure from the front edge of the casing straight back to any obstruction like a crank or lock.
If the depth falls short of 2 inches, the headrail sticks out past the frame or won’t clear window hardware. In that case switch to an outside mount rather than forcing it. Note any handles, cranks, or alarm sensors inside the recess too, since they steal usable depth. Confirm the depth before you measure anything else, because it decides whether inside mount is even possible.
How Do You Measure the Width for Inside Mount?
Measure the width at three heights, top, middle, and bottom of the opening, and report the narrowest number. Windows drift out of square over time, so the smallest width guarantees the blind clears the frame at every point. Read each measurement to the nearest eighth of an inch and hold the tape level against the inside faces of the casing.
Do not subtract anything from your width. The factory automatically deducts about a quarter to a half inch for clearance, so if you deduct too, the blind ends up too narrow and light leaks down both sides. This is the single most common inside-mount error. Report the exact opening and let the manufacturer handle the tolerance for a snug fit.
How Do You Measure the Height for Inside Mount?
Measure the height at three points, left, center, and right, from the top inside of the frame to the sill. For inside mount you generally report the longest of the three so the blind reaches the sill fully. A metal tape held straight and taut gives a cleaner reading than a cloth one that can sag mid-drop.
If there’s no sill, measure to the point where you want the blind to end. Some people prefer the exact height with no deduction and let the blind rest on the sill; others deduct a small amount to keep the bottom rail from dragging. Check the manufacturer’s guidance, since a few take the height deduction for you the way they do width. Record all three readings so you can see how far out of square the frame runs.
What Mistakes Ruin an Inside Mount Fit?
The biggest mistake is subtracting for clearance when the factory already does it. Deduct half an inch yourself on top of the factory’s cut and the blind arrives too narrow, with a visible gap of light on each side that defeats the built-in look. Report the raw opening every time.
The second is measuring only once and missing an out-of-square frame. A window that’s a quarter inch wider at the bottom than the top will bind a blind cut to the top reading, so the three-point check is non-negotiable. The third is ignoring depth-robbing hardware: a window lock or crank inside the recess can block the headrail even when the raw depth measures 2 inches. Account for those before you order.
What You’ll Need
The tools below are ranked by owner rating, and for inside mount work you want a rigid tape that holds level across a window opening. A 25-foot retractable handles any window with room to spare, and a fraction-marked blade makes reading to the eighth easier. Start with #1 for a wall-mountable adhesive stick tape.

- Clear, easy-to-read graduations in standard imperial measurements
Cons
- Permanent adhesive means you cannot easily reposition once applied
- Only available in 6-foot length which may be too short for larger work surfaces
- Right-to-left orientation requires adjustment if you typically read left to right
If you have a workshop, craft room, or dedicated project space, this adhesive tape measure changes how you work. Instead of constantly picking up and setting down a tape measure, you get instant reference measurements right on your table surface. It stays put while you slide materials across it, mark cuts, or line up assembly work.
The steel construction means it will not stretch or warp like cheaper alternatives, and the polyurethane coating protects it from scratches, sawdust, and general workshop wear. You can cut it to fit your exact table width, which is perfect for smaller workbenches or craft tables where a full 6 feet is too much.

For hanging curtains, measuring furniture spacing, or checking door frames, that solo capability is a genuine time-saver.
The color-coded fraction markings are smarter than they sound. Instead of squinting at tiny black lines that all look the same, you get alternating colors and heights that make 1/4, 1/2, and 3/4 inch marks instantly recognizable. If you have done any measuring in dim light or at awkward angles, you will appreciate how much faster this makes the job. The rubber overmold is thick enough to survive drops onto concrete without cracking, and it fits comfortably in your hand during long measuring sessions.
If you want a tape measure that works well for solo projects without paying $30+ for a premium brand, this one delivers.
Styles it works with: Modern Farmhouse, Industrial, Traditional, Minimalist
Best placed in: Tool drawer in kitchen or garage, hung on pegboard in workshop, stored in entryway catch-all basket for quick home repairs

The 25-foot blade handles most home projects in one pull, from measuring a gallery wall to checking if that sofa will fit through the doorway.
What makes it genuinely useful for home decor work is the dual measurement system. When you are assembling flat-pack furniture with metric instructions but buying lumber in inches, you don't need to pull out your phone for conversions. The thumb lock is smooth enough to use one-handed when you are holding a level or picture frame in the other.

The FRCTLNKG adhesive measuring tape sits at 4.6 for stick-on reference use, and the TMWEFUSC two-pack of 25-foot dual-scale tapes rounds it out at 4.2, the honest low here, giving you a metric-and-imperial backup.
Frequently Asked Questions
Do I subtract for clearance on inside mount blinds?
No. The factory deducts about a quarter to a half inch automatically. Report the exact opening width. Subtracting yourself leaves the blind too narrow with light gaps on both sides.
How much depth do inside mount blinds need?
At least 2 inches of flat, unobstructed depth for a flush headrail on most blinds. Less than that, and the headrail protrudes or hits window hardware, so switch to an outside mount.
Why do I measure the window at three points?
Because frames rarely stay perfectly square. Measuring width at top, middle, and bottom and using the narrowest ensures the blind clears the frame everywhere instead of binding at the tight spot.
Do I use the narrowest or widest width measurement?
The narrowest. For height, generally the longest. Narrowest width guarantees clearance side to side, and the longest height reaches the sill for full coverage on an inside mount.
What if a window crank or lock is inside the frame?
It steals usable depth. Measure to the obstruction, not the back of the casing. If hardware blocks the 2-inch minimum, choose an outside mount so the blind clears it entirely.
Can I do an inside mount on an out-of-square window?
Yes, but it shows the gap. If the frame is off by more than about a quarter inch, an outside mount hides the crookedness better while an inside mount highlights it.
Width or height first when I order?
Width first, then height, almost universally. A blind listed 30 by 48 means 30 inches wide by 48 tall. Reversing the two orders a blind for the wrong orientation.
Bottom Line
Inside mount blinds fit cleanly when you confirm 2 inches of depth, measure the opening at three points, and report the exact numbers without deducting for clearance. Use the narrowest width and the longest height, and account for any crank or lock that eats into the recess. The factory takes the tolerance, so your job is an accurate raw measurement, not a corrected one. Measure twice at three points each, and the blind drops into the frame with no binding and no light gap.
