How to Shorten PVC Venetian Blinds

PVC Venetian blinds are a popular window covering option, but their standard sizing doesn't always fit every space perfectly. Fortunately, shortening wider blinds is a simple DIY project to achieve an ideal custom fit. With the right preparation and tools, you can trim blinds down to size in your home easily.

 

Measure the Area

Start by carefully measuring the exact width of the window or area you need covered. Note the width at the very top, middle and bottom since openings are rarely perfectly square.

Use the smallest measurement to determine the cut length needed for the blinds to fit properly. It's easier to trim more later if needed, but you can't add length back!

 

Gather Materials

You'll need:

Metal snips, shears or hacksaw

Tape measure

Pencil

Sandpaper (optional)

Duct tape (optional)

Avoid using scissors which can bend the rigid vinyl. Quality snips or shears will cut through cleanly without cracking or crushing.

 

Mark Cut Lines

With the blinds fully extended, carefully measure and mark straight cut lines across all the slats. Ensure the lines are perfectly perpendicular for even trimming.

Be sure to account for where you want the operating cords to fall as well so shortening doesn't hinder function.

 

Cut Evenly Across

With the blinds securely clamped or held steady, position your cutting tool at the trim mark. In one smooth, straight motion, slice firmly across to remove excess length.

Applying too much pressure can deform the cut, so let the shears blade do the work. Cutting patiently prevents mistakes.

 

Refine Edges

For refined results, lightly sand any tiny burrs left after cutting. This leaves a clean, smooth edge. Wipe away lingering pencil marks too.

Or quickly brush edges with a dry paintbrush to whisk away PVC particles for a tidier appearance.

 

Prevent Fraying

To reinforce ends and prevent fraying over time, apply a short piece of strong duct tape across the tips. Firmly smooth onto all slats for security and structure.

This helps significantly improve durability so the shortened blinds maintain integrity with regular use.

 

Rehang and Enjoy

The tailored PVC Venetian blinds can now be rehung in position to perfectly fit the window space! Enjoy the customized size and access full blind functionality.

Properly measured and smoothly cut, quality narrower blinds enhance any room's decor for years to come.
