How to Install Blinds Inside Window
Installing window blinds is one of the easiest ways to improve your home. It helps block sunlight, adds privacy, and makes a room look neat. Many people choose inside mount blinds because they fit neatly within the window frame. If you’re wondering how to install blinds inside window, this guide will walk you through each step in a way that’s easy to understand and follow. Whether you’re doing it for the first time or replacing old blinds, you’ll learn how to do it the right way.
Why Blinds Are a Smart and Stylish Window Solution
Blinds are more than just window coverings. They help you control light, protect furniture from sun damage, and give you privacy whenever you need it. Blinds also come in many colors and styles, so you can match them to your room’s look.
Inside mount blinds are a favorite for many homeowners. They sit within the window frame, giving a clean and tidy look. If you want something that doesn’t stick out or take up extra space, inside-mounted blinds are a great option.
They are especially popular for small rooms or places where curtains may be too bulky. With just a little time and the right tools, anyone can put up blinds and change the feel of a room.
What Does “Inside Mount” Mean for Window Blinds?

There are two main ways to hang blinds: inside mount and outside mount.
Inside mount means the blinds go inside the window frame. This gives a sleek, built-in look.
Outside mount means the blinds are hung on the wall or trim, covering the entire window and a bit more.
Inside mount is great if you want your window trim to show. It also works well when your window frame is deep enough to hold the blind.
So when we say “installing blinds inside mount,” we mean you’re placing the blind brackets inside the window frame. It’s neat, space-saving, and very common in modern homes.
Getting Ready: What You Need to Install Blinds Inside a Window Frame
Before you start the job, you need a few simple tools and materials. Here's what you'll need:
Tools:
Pencil
Measuring tape
Screwdriver or power drill
Screws (usually come with the blinds)

Level (to keep everything straight)
Most blinds that are sold today are easy-to-install window blinds. They come with brackets and screws included. Just follow the instructions and go step by step.
Make sure you also open and read any guide that comes with your blinds. It can help you understand how your particular model works.

Measuring Your Window for Inside Mount Blinds the Right Way
Getting the right measurement is very important. It helps your blinds fit perfectly. Here’s how to measure your window:
Step 1: Measure the Width
Measure the inside width of the window at the top, middle, and bottom.
Write down the smallest number. That’s the width you’ll use.
Step 2: Measure the Height
Measure the height from top to bottom on the left, middle, and right.
Again, use the smallest number.
This helps the blinds fit neatly and work well without bumping into anything. If your blinds are a bit too wide, don’t worry. Many stores sell cut to fit window blinds.
