How to Expertly Measure Vertical Blind Replacement Slats — The Easy Tip-to-Tip Guide
If you’re replacing vertical blind slats, getting the right measurement is crucial for a smooth, professional look. The good news? You don’t need to worry about mounting holes or hardware—just follow this simple tip-to-tip method.
Step-by-Step: How to Measure Your Vertical Blind Slats (Tip to Tip)
-
Remove One of Your Existing Slats
Choose a slat that fits properly and hasn’t been trimmed or warped. This ensures you're measuring the correct length. -
Lay It Flat
Place the slat on a hard, flat surface like a floor or table. Avoid bending or curling. -
Measure the Total Length from Top to Bottom
Using a metal measuring tape, measure from the very top edge of the slat to the very bottom edge—tip to tip.
✅ Do not worry about where the mounting hole is or any weights at the bottom—just measure the full length as it hangs.
Using Fractions for Precision
Blinds don’t always measure in whole numbers. If your slat measures between inches, use the nearest 1/8" increment. Here’s a quick reference:
-
1/8"
-
1/4"
-
3/8"
-
1/2"
-
5/8"
-
3/4"
-
7/8"
Example: If your slat is just past 35" but not quite 35 1/4", it’s likely 35 1/8".
Pro Tips:
✅ Measure from tip to tip — top edge to bottom edge
✅ Always double-check — even 1/8" makes a difference
✅ If slats are different lengths, go with the most common one in the set
✅ Measure at least 2–3 slats to confirm consistency
Final Thought:
Measuring your replacement slats is simple when you use the tip-to-tip method. Just follow the steps, use 1/8" increments, and you’ll get a perfect fit—no guesswork needed.
