How to Measure for Replacement Windows: Tips for Lincoln and Omaha, NE

According to money.com, the average return on investment for a window replacement is around 65% of the project cost. So, what does this indicate? That means a well-executed upgrade can boost your home’s value.

However, in the Midwest, where historic architecture meets unpredictable weather, accurate window sizing isn’t only about aesthetics. It’s about performance and energy efficiency.

If you’re wondering how to measure for replacement windows, you’re not alone. Many Omaha & Lincoln homeowners attempt to DIY their window replacements, only to encounter expensive errors down the road.

In this step-by-step window measurement guide, we’ll break down exactly what you need to know to get precise measurements and make smart decisions for your home.

Why Accurate Window Measurements Matter (Especially in the Midwest)

Nebraska experiences everything from bitter cold winters to humid spring and scorching hot summers. Properly fitted windows play a major role in:

• Insulation
• Sound control
• Weather resistance

In Omaha neighborhoods like Dundee, Millard, and Elkhorn, many homes feature unique window shapes and frame styles that demand custom window fittings. Poor measurements can lead to gaps, drafts, leaks, and even water damage.

That’s why accuracy is your best defense. Whether modernizing a ranch in Westside or restoring a bungalow in Benson, understanding how to measure is your first step toward a successful window replacement.

Step 1: Understand Your Window Type

Before you start measuring, identify what kind of window you’re replacing. Is it a single-hung, double-hung, casement, or slider? Learn about each of the window types.

Each window type may have a different measuring method. In Omaha, older homes often have wooden double-hung windows, while newer homes might feature vinyl casement models.

Knowing the style helps determine the right replacement unit and ensures your Omaha window replacement goes smoothly.

Step 2: Measure the Width

To ensure your replacement window fits snugly and functions properly, start by measuring the window opening. Precision in this first step will prevent future headaches.

Take three horizontal measurements:

• Top
• Middle
• Bottom

Measure from jamb to jamb- inside trim to inside trim (not casing to casing) and write down the shortest measurement to ensure the new window fits. Use a metal tape measure for accuracy and keep it level.

This step is crucial when working on brick homes in neighborhoods like Aksarben or those with thick plaster interiors.

Step 3: Measure the Height

Once you’ve measured the width, it’s as important to measure the height with care. Height measurements help ensure your replacement window will sit as it should and seal tightly.

Take three vertical measurements:

• Left side
• Center
• Right side

Measure from the high point of the sill to the top of the opening (head jamb). Record the shortest height.

Don’t include trim or sashes. You’re measuring the window frame opening itself.

Homes in Midtown and South Omaha often have slightly uneven window openings. That makes these three-point checks even more important.

Step 4: Double Check Your Window is Square

After confirming the width and height are consistent, it’s time to check for squareness. This ensures your new window will operate without gaps or stress.

Measure diagonally from corner to corner:

• Top-left to bottom-right
• Top-right to bottom-left

If the two measurements are within 1/4 inch, your window opening is square. If not, your installer may need to shim or adjust.

Omaha homes built before the 1960s often shift over time, making this check essential for accurate window sizing.

Tips for Getting Custom Window Fittings in Omaha

Custom windows are popular in upscale Omaha homes, especially in places like Regency or The Ridges. To get them right:

• Take multiple sets of measurements
• Consult a professional for unique shapes (arches, circles, bay windows)
• Ask about energy-efficient glass packages designed for Midwest climates
• Confirm local permit requirements

Always prioritize function alongside aesthetics. This is very important to ensure you will have no regrets later.

What If You Get the Measurements Wrong?

Measuring for replacement windows isn’t just about numbers; it’s about precision. A small mistake now can create big problems later.

Incorrect measurements can lead to:

• Installation delays
• Increased labor costs
• Improper sealing
• Voided warranties

That’s why many homeowners in Eastern Nebraska choose companies like Pella Windows & Doors of Omaha and Lincoln for their window installation services. Professional measurement ensures the right fit the first time.

When to Consider Professional Help

Homeowners in Omaha often enjoy tackling projects themselves, especially when it saves time and money. But when it comes to more complex upgrades, expert help matters.

DIY is great for minor fixes, but you need an expert when you’re dealing with:

• Historic homes
• Large or high windows
• Specialty glass or trim

Many Omaha & Lincoln residents schedule FREE in-home consultations to avoid expensive mistakes. Local professionals know how to account for Nebraska’s:

• Freeze/thaw cycles
• Wind loads
• Sun exposure

What Makes a Window “Right” for Omaha & Lincoln?

Choosing windows isn’t only about fit. It’s about finding features that hold up to our region’s weather and architectural character. Look for:

• Low-E glass to minimize heat gain
