When you are ready to refresh your space with custom blinds, accurate window measurements are the foundation of a smooth and successful installation. Measuring may seem intimidating at first, but with a calm, step-by-step approach, you can feel empowered and confident throughout the process.

Why Accurate Measurements Matter for Custom Blinds

Precise measurements ensure your custom blinds fit beautifully. This gives your windows a polished appearance, prevents issues during installation, and helps your window coverings perform as they should. Whether your goals include added privacy, energy efficiency, or a fresh interior look, a perfect fit is essential.

Accurate measurements support:

• Smooth and stress-free installation
  
• Proper light control
  
• Enhanced insulation
  
• A clean and cohesive aesthetic
  

This step also helps you feel fully engaged in the transformation of your space.

What You Need Before You Begin

Gathering the right tools before you begin can help you feel grounded and ready.

• A steel measuring tape
  
• A pencil and a notepad
  
• A level if you have one
  
• A clear idea of whether you want an inside mount or an outside mount
  

Taking a moment to prepare creates a more relaxed and focused experience.

Step 1: Choose Inside Mount or Outside Mount

Choosing between an inside mount and an outside mount sets the tone for the visual style of your window treatments.

Inside Mount

Inside mounts place the blinds within the window frame. This creates a simple, modern, and minimal look that enhances the clean lines of your home.

Best for:

• Deep window frames
  
• Sleek and contemporary styles
  
• Minimalist spaces
  

Outside Mount

Outside mounts place the blinds above or around the window frame. This creates full coverage and can help make windows appear larger and more dramatic.

Best for:

• Shallow frames
  
• Maximum light blocking
  
• Enhanced privacy
  

Rick’s Blinds offers free in-home consultations to help Kansas City homeowners decide which option aligns best with their home.

Step 2: How to Measure for Inside-Mount Custom Blinds

When measuring for an inside mount, take your time and work closely with the natural structure of the window frame.

Measure the Width

Take dimensions for the width at the top, middle, and bottom of the window. Use the narrowest number as your final measurement. This ensures the blinds operate smoothly without rubbing against the frame.

Measure the Height

Take dimensions for the height on the left side, the center, and the right side. Use the tallest of the three measurements.

Measure the Depth

Depth determines whether the blinds you want can fit comfortably inside the frame. This is especially important for shutters, cellular shades, and roller shades.

Step 3: How to Measure for Outside-Mount Custom Blinds

Outside mounts offer wider coverage and can dramatically change the feel of a room.

Measure the Width

Take dimensions for the total area you want the blinds to cover. Add two to three inches on each side for full coverage and better insulation.

Measure the Height

Measure from the top of where you want the blinds installed down to the point where you want them to end. Outside mounts often make windows look larger and create a strong visual impact.

Step 4: Common Measurement Mistakes to Avoid

These supportive reminders can help you measure with confidence:

• Avoid rounding your measurements
  
• Avoid relying on fabric tape measures
  
• Avoid skipping depth measurements
  
• Avoid assuming your windows are perfectly square
  

Being mindful of these details leads to a more accurate order and a smoother installation.

Step 5: When to Bring in a Professional

Even if you enjoy DIY projects, partnering with a professional can save time and stress. Rick’s Blinds has been helping Kansas City homeowners since 2001 and offers free, no-pressure in-home consultations.

A professional is especially helpful when:

• You plan to install motorized blinds
  
• You are layering curtains with shades
  
• You want design guidance and expert recommendations
  

Bringing in a specialist is a powerful way to support the vision you have for your home.

Common Questions About Measuring Windows for Blinds

What is the most important measurement?

Width is the most important for inside mounts because even small differences affect how the blinds operate.

Do I include trim in my measurement?

For inside mounts you do not. For outside mounts you should.

What if my window is not perfectly square?

Use the narrowest width and the tallest height. This is normal and expected.

Do blinds and shades require different measurements?

The measuring process is similar but shades often require deeper window frames. Always check depth.

Can I install blinds myself?

Yes you can, but professional installation ensures a perfect fit and is recommended for motorized or specialty window treatments.

Trending Considerations for 2025

As modern window treatments evolve, homeowners are increasingly choosing:

• Motorized blinds
  
• Eco-friendly materials
  
• Layered treatments
  
• Energy efficient cellular shades
  

These options often require more precise depth and width measurements. Staying aware of trends helps you plan ahead and choose window coverings that feel aligned with the future of home design.
