Installing Window Shades Made Easy
Installing window shades doesn't have to be complicated. Whether you're upgrading your home's privacy, controlling light, or enhancing your interior design, this comprehensive guide will walk you through the entire installation process.

What You'll Need
- Window shades (inside or outside mount)
- Measuring tape
- Pencil
- Level
- Drill with appropriate drill bits
- Screwdriver
- Mounting brackets (usually included)
- Screws and anchors (if not included)
Step 1: Measure Your Window
Accurate measurements are crucial for a perfect fit. Decide whether you want an inside mount (inside the window frame) or an outside mount (on the wall above the window).
For inside mount: Measure the width of the window opening at the top, middle, and bottom. Use the narrowest measurement and subtract 1/4 inch for clearance. Measure the height from the top of the opening to the sill.
For outside mount: Measure the width you want the shade to cover, typically 1-3 inches wider than the window frame on each side. Measure the height from where you want the top of the shade to where you want it to end.

Step 2: Mark Bracket Positions
Using your pencil and level, mark where the mounting brackets will go. For inside mounts, position brackets at the top corners of the window frame. For outside mounts, position them on the wall 4 inches above the window frame and extending beyond the frame width.
Use a level to ensure your marks are perfectly horizontal – this prevents your shade from hanging crooked.

Step 3: Install the Mounting Brackets
Drill pilot holes at your marked positions. If you're drilling into drywall, use wall anchors for extra support. Attach the mounting brackets using the provided screws, making sure they're secure and level.

Step 4: Attach the Shade
Most modern window shades simply click or snap into the mounted brackets. Follow the manufacturer's specific instructions, but generally:
- Insert one end of the headrail into the bracket
- Push the other end into the opposite bracket
- You should hear or feel a click when it's secure

Step 5: Install the Valance (Optional)
If your shade comes with a decorative valance, clip it onto the headrail according to the manufacturer's instructions. This covers the hardware for a clean, finished look. Some shades' valance goes with the shade, like the bamboo shade.
Step 6: Test Your Shade
Raise and lower your shade several times to ensure smooth operation. For cordless shades, gently pull down to lower and push up to raise. For corded shades, test the cord mechanism.
Pro Tips for Perfect Installation
- Always measure twice, cut once – or in this case, order once
- Use a stud finder to locate wall studs for the most secure outside mount installation
- For wide windows (over 48 inches), consider using a center support bracket
- Keep the shade raised for the first 24 hours to help set the pleats
- Clean your window before installation for the best appearance

Frequently Asked Questions
Q: What is the difference between inside mount and outside mount window shades?
Inside mount shades are installed within the window frame for a clean, built-in look. Outside mount shades are mounted on the wall above the frame, ideal for covering larger areas or maximizing light blockage.
Q: How do I measure for inside mount window shades?
Measure the width at the top, middle, and bottom of the window opening — use the narrowest measurement and subtract ¼ inch for clearance. Measure the height from the top of the opening to the sill.
Q: Can I install window shades without drilling?
Yes. Tension-mounted or adhesive-mounted shades are available for renters or those who prefer a no-drill solution. However, for custom or heavier shades, bracket installation with screws is recommended for long-term stability.
Q: How long does it take to install window shades?
Most single-window installations take 15–30 minutes with basic tools. A full room with multiple windows typically takes 1–2 hours.
Q: Do Curtarra window shades come with installation hardware?
Yes. All Curtarra custom shades include mounting brackets, screws, and a valance (where applicable). For specialty walls (concrete, tile), additional anchors may be required.
Q: What should I do if my shade is crooked after installation?
Remove the shade from the brackets and re-check your bracket alignment with a level. Even a 1–2mm difference can cause visible tilt. Re-mark and re-drill if necessary.
