Buying Guide

Everything you need to know before buying window treatments — measuring, choosing, and installing safely.

How to Measure Your Windows

Getting measurements right is the difference between a perfect fit and a costly mistake.

Inside Mount vs. Outside Mount

Inside Mount: The shade fits inside the window frame. Cleaner, more built-in look. Requires adequate frame depth.

Outside Mount: The shade mounts on the wall or trim above the window. Better light blocking, easier to install, required for some window types.

Tools You Need

  • Steel measuring tape (not cloth)
  • Pencil and paper
  • A helper for large windows
  • Note: measure twice, order once

Key Measurement Rules

  • Measure width in 3 places (top, middle, bottom). Use the smallest width.
  • Measure height in 3 places (left, center, right). Use the tallest height.
  • For inside mount: subtract 1/4" from each dimension for clearance.
  • For outside mount: add 2–3" to each side for light blocking.
  • Always measure to the nearest 1/8".

Step-by-Step Measuring Process

  1. Decide mount type — Inside mount looks cleaner but requires at least 2" of frame depth. Outside mount is more forgiving and blocks light better.
  2. Measure width first — Measure across the top, middle, and bottom of where the shade will go. Record all three measurements. Use the narrowest.
  3. Measure height — Measure from the top mounting surface to the bottom (for inside mount, measure to the window sill). Use the tallest measurement.
  4. Double-check — Measure again. Window sizes can be deceiving — older homes especially can have significant size variations between windows in the same room.
  5. Round appropriately — Most manufacturers want measurements to the nearest 1/8". Round up slightly for width if between sizes.

💡 Pro Tip: Not All Windows Are the Same Size

Even in the same room, windows can vary by 1/4" or more. Always measure each window individually — never assume two windows are the same size. Order each shade separately with its own measurements.

Cordless vs. Motorized: What's Right for You?

Choose Cordless If:

  • You're on a budget — cordless starts at $45–$90
  • Children are over 6 and reliably understand not to play with window treatments
  • You want simple, reliable operation without electronics
  • Windows are in easy reach — you can push/pull manually
  • You're replacing existing corded blinds in a non-nursery space
Cordless Pros:

No batteries, no WiFi, no hub, no electronics to fail. Works forever without any setup.

Choose Motorized If:

  • Children under 6 are in the home — this is the safest option
  • Windows are hard to reach (high ceilings, large spans)
  • You want smart home integration (Alexa, HomeKit, Google Home)
  • Scheduling automation is important to you
  • You want the ultimate in convenience and safety
Motorized Pros:

Complete automation, app control, voice control, scheduling. No physical operating mechanism = maximum safety.

Smart Home Integration Guide

Motorized shades work with your existing smart home ecosystem. Here's what you need to know.

🅰️ Amazon Alexa

Most motorized shades work with Alexa through the manufacturer's app or a smart home hub. Look for "Works with Alexa" in the product listing.

  • Shade setup via manufacturer app
  • Enable skill in Alexa app
  • Create groups ("living room shades")
  • Voice commands: "Alexa, close bedroom shades"

🅶 Google Home

Google Home integration works similarly — set up via manufacturer app first, then link to Google Home for voice control.

  • Set up via manufacturer app first
  • Link in Google Home app
  • Create rooms and groups
  • Routines: "Hey Google, good morning" opens shades

🍎 Apple HomeKit

HomeKit requires specific compatibility. Look for "Works with HomeKit" or "HomeKit Ready" — not all motorized shades support it.

  • Requires HomeKit-compatible shades
  • Add via Apple Home app or manufacturer app
  • Siri voice control
  • Automation with other HomeKit devices

📱 Remote & App Control

Even without smart home integration, most motorized shades come with a dedicated remote control and smartphone app for direct control.

  • Remote: wall-mounted or handheld
  • App: iOS and Android
  • Control multiple shades from one remote
  • Geofencing: auto-close when you leave home

🔧 Hub Requirements

Some motorized shades require a dedicated hub or bridge (sold separately). For example, Lutron Serena shades need the Lutron Smart Bridge. Other shades connect directly via WiFi without a hub. Check the product listing before buying — budget for the hub if needed.

Budget Guide by Window Size

Window Width Cordless Option Motorized Option Notes
Small (under 30") $35–$65 $100–$180 Small windows are the most affordable. Cellular and roller shades work well.
Standard (30"–48") $50–$110 $150–$280 Most common window size. Wide range of options in both categories.
Wide (48"–72") $80–$160 $200–$400 Wide windows may need multiple shades or specialty wide-format shades.
Extra Wide (over 72") $120–$250+ $300–$600+ Consider multiple linked shades or custom sizing for best results.

💰 What's Included in the Price?

  • Shade itself (fabric + hardware)
  • Mounting brackets
  • Installation hardware
  • Remote control (motorized)
  • Manufacturer warranty
  • Power adapter (motorized)

Not included: Professional installation (if needed), smart home hub/bridge, solar panel accessory.

Top 10 Mistakes to Avoid

1. Wrong Measurements

Measuring wrong is the #1 reason for returns. Measure multiple times, in multiple spots, and always use the smallest width / tallest height rule.

2. Not Knowing Mount Type

Inside vs. outside mount changes everything — dimensions, look, and light blocking. Decide this before you measure.

3. Ignoring Frame Depth

Inside mount requires adequate frame depth (usually 2" minimum for cellular shades). If your frame is shallow, go outside mount.

4. Buying Corded for a Child's Room

If children under 6 will be in the room, only cordless or motorized is acceptable. No exceptions. Budget for safety.

5. Not Accounting for Operating Clearance

Shades need clearance to operate. Inside mount shades that are too deep in the window frame can hit the sill when lowered. Leave 1/4" clearance.

6. Choosing Real Wood in Bathrooms

Moisture and humidity will warp real wood blinds. Use faux wood in bathrooms, kitchens, and other high-humidity spaces.

7. Ignoring Light-Blocking Needs

If you need dark conditions for sleep (nurseries, bedrooms), make sure you buy blackout fabric — light-filtering won't be dark enough.

8. Forgetting About Cordless Wand Length

Some wood blinds with "cordless" lift still use a wand for tilt. Make sure the wand length is appropriate for your window height.

9. Not Budgeting for Hub/Smart Setup

Motorized shades that require a hub add $50–$150 to the total cost. Factor this in before you buy.

10. Assuming All Windows Are the Same Size

Never assume. Older homes in particular can have significant size variations between windows in the same room. Always measure each individually.

Common Questions

Cellular shades typically need 2" of frame depth for inside mount. Roller shades can sometimes work with less (1.5"). Measure your frame from the front face to the window glass — that's your available depth. If it's less than 1.5", go with outside mount.
Most residential window treatments are designed for DIY installation. If you're comfortable using a drill and measuring tape, you can install cordless and motorized shades yourself. The most complex part of motorized shade installation is connecting to power/WiFi — but most products come with clear instructions. For very large windows or custom configurations, professional installation may be worth the cost.
Battery life depends on shade size, weight, and usage frequency. Most rechargeable motorized shades need recharging every 6–12 months. Some systems offer solar charging panels that can extend this indefinitely or reduce the need for manual recharging. If you're installing new motorized shades, budget for solar charging accessories if available.
Light-filtering fabric allows diffused light to pass through while providing privacy during daytime — people outside can't see in, but you still have natural ambient light. Blackout fabric is completely opaque, blocking all light from passing through. Blackout is essential for nurseries, home theaters, and people who need complete darkness for sleep.
No — it depends on the brand. Some brands connect directly via WiFi (Akane, some Smart Home shades) and don't need a separate hub. Others (Lutron Serena, some SmartThings-compatible shades) require a specific bridge or hub. Check the product listing before buying.
