You can replace individual slats without buying new blinds

If your blinds have a few broken or bent slats, you do not need to replace the entire blind. Most vertical and horizontal blinds use slats that slide into a track or clip onto a rail, which means you can remove the damaged ones and slide new slats in their place. The process takes about 15 minutes per slat and costs far less than a new blind.

The method depends on your blind type. Vertical blinds usually have slats that hook onto a carrier rail at the top and hang freely. Horizontal blinds (venetian blinds) have slats threaded through cords on both sides. Once you understand which type you have, the replacement is straightforward.

Key Takeaways

  • Vertical blind slats unhook from the carrier rail at the top and slide out sideways; horizontal blind slats thread through cords and require you to loosen the cord tension first.
  • Measure your existing slat width, length, and thickness before ordering replacements, because slats come in standard sizes but your blind may use a less common one.
  • You can buy individual replacement slats from the blind manufacturer, a hardware store, or online retailers that sell blind parts.
  • Horizontal blinds require you to re-thread the cords through the new slat, which is the most time-consuming step but does not require tools.

Identify your blind type and how slats attach

Vertical blinds have slats that hang from a track at the top. Each slat has a hook or clip at the top that slides into a carrier rail. To remove a slat, you straightforward unhook it from the rail and slide it out sideways. The slats do not connect to anything at the bottom, so removal is quick.

Horizontal blinds (venetian or mini blinds) have slats stacked flat and held in place by cords running through holes on both sides of each slat. The cords are what hold the slats in their stack. To remove a slat, you must first loosen the cord tension so the slat can slide out of the cord holes. This is the main difference in difficulty between the two types.

Measure your slat before ordering a replacement

Slat width, length, and thickness all matter. Width is the measurement across the face of the slat (usually 3.5 inches for horizontal blinds, but can vary). Length is the distance from top to bottom when the blind is fully extended. Thickness is how thick the slat material is—usually 0.125 inches for horizontal blinds.

Measure the width by holding a ruler across the slat face. Measure the length by extending the blind fully and measuring from the top of the slat to the bottom. Write down all three numbers. If you have the blind's original paperwork or can find the brand name on the headrail, you can also call the manufacturer and give them the model number—they will tell you the exact slat size.

Standard sizes exist, but not all blinds use them. A slat that is slightly too wide will not slide into the track; one that is too narrow will rattle. Ordering the wrong size wastes money and time.

Remove a damaged slat from a vertical blind

Start at the top of the blind. Look at the carrier rail—you will see a series of hooks or clips spaced evenly along it. Each slat hangs from one of these. Locate the hook holding your damaged slat.

Gently lift the slat upward until the hook at the top clears the carrier rail. Once the hook is free, slide the slat sideways out of the blind. It should come out easily; if it does not, check that the hook is fully clear of the rail. Set the damaged slat aside.

If the slat is bent but not broken, you may be able to straighten it by laying it flat on a table and explore gentle pressure, but replacement is usually faster and more reliable.

Remove a damaged slat from a horizontal blind

Horizontal blinds are trickier because the slats are threaded onto cords. Before you remove anything, you must release the cord tension so the slat can slide free.

Look at the bottom of the blind. You will see a wand or cord that controls the tilt. Pull it all the way in one direction to tilt the blind fully open. This loosens the tension on the cords running through the slats. Now look at the side of the blind where the cords attach to the bottom rail. You should see a small clip or knot holding the cords in place. Loosen or release this clip slightly—just enough that the cords have slack.

Now slide the damaged slat sideways out of the cord holes. The cords should have enough slack to let it pass. Once the slat is out, you can re-tighten the clip.

Install the new slat

For vertical blinds, straightforward reverse the removal process. Slide the new slat into the space where the old one was. Make sure the hook at the top is aligned with the carrier rail, then lift the slat upward until the hook catches on the rail. The slat should hang straight and level with the others.

For horizontal blinds, the process is longer because you must re-thread the cords. Loosen the cord tension again by tilting the blind fully open and releasing the clip at the bottom. Take the new slat and thread the left cord through the left hole, then the right cord through the right hole. Slide the slat all the way into position between the slats above and below it. Once it is in place, re-tighten the clip at the bottom and tilt the blind to normal position. The cords should now hold the new slat in place.

Check that the new slat is level and aligned with the others. If it tilts or sits higher than its neighbors, the cords may not be threaded evenly—loosen the clip again and adjust.

Where to buy replacement slats

The blind manufacturer is the best source if you know the brand. Most manufacturers sell replacement slats directly or through their website. You will need the blind model number, which is usually printed on the headrail or in your original paperwork.

Hardware stores like Home Depot and Lowe's stock replacement slats for common blind sizes. Bring your measurements and the old slat if possible so staff can match it. Online retailers like Amazon and specialty blind parts sites also carry slats, though shipping times vary.

If you cannot find an exact match, a slat that is slightly narrower (by 0.125 inches or less) will usually work in a vertical blind, though it may rattle slightly. For horizontal blinds, the fit must be exact because the slat threads onto cords.

Frequently Asked Questions

Can I replace just one slat or do I have to replace them all?

You can replace just one slat. Blinds are designed so individual slats can be swapped out without affecting the others. The new slat does not have to match the color or finish of the existing ones, though most people prefer it to.

What if I cannot find the exact slat size?

For vertical blinds, a slat that is 0.125 inches narrower will usually fit, though it may rattle slightly. For horizontal blinds, the fit must be exact because the slat threads onto cords—an oversized slat will jam, and an undersized one will fall out. If you cannot find your size, contact the blind manufacturer by model number.

Do I need tools to replace a slat?

No. Vertical blind slats unhook by hand. Horizontal blind slats require you to loosen a clip or knot, which you can usually do by hand or with a small flathead screwdriver. No power tools are needed.

How long does it take to replace a slat?

Vertical blinds take about 5 to 10 minutes per slat. Horizontal blinds take 10 to 15 minutes per slat because you must re-thread the cords. If you are replacing multiple slats, the time per slat decreases slightly as you get faster.

What if the cord on my horizontal blind breaks while I am replacing a slat?

If a cord breaks, you will need to re-cord the entire blind, which is more involved than replacing a single slat. This usually requires removing all the slats, threading new cord through each one, and re-attaching them to the headrail. Many people choose to replace the entire blind at this point rather than re-cord it. If this happens, contact the manufacturer to see if they offer re-cording kits or services.
