How to Measure a Window: A General Guide

Welcome to our guide on how to measure a window. This article aims to help those who are planning to renovate or replace their windows to properly measure the size of their new windows. Measuring a window may seem like a simple task, but it requires precision and accuracy to ensure the perfect fit.

Steps to measure a window

Step 1: Determine the type of window

Before measuring, it is crucial to determine what kind of window needs to be measured. Are you measuring a single or double-hung window? Is it a sliding window or a casement window? Each type of window has a different measurement process, so it’s essential to be aware of the window type.

Step 2: Measure the width

To measure the width of the window, take the measurement from the inside of the window jamb on the left side to the inside jamb on the right side. It is advisable not to take the measurement from the window trim or casing as it may lead to incorrect measurements.

Step 3: Measure the height

Measure the height of the window from the bottom of the sill to the top of the window frame. Ensure that you measure from the highest point of the sill if there is a slope.

Step 4: Find the depth

Measuring the depth of the window is essential for determining the size of the frame. Measure the distance between the interior and exterior trim to determine the depth of the window.

Step 5: Measure the diagonal

Measure the diagonal distance between the top left and bottom right corners and then top right and bottom left corners. The two measurements should be the same if the window is a square. If the measurements differ, take the mean measurement.

Step 6: Identify the frame material

Identifying the frame material is essential as it may affect the measurement process. Window frames can be made from different materials such as vinyl, wood, aluminium, or fibreglass.

Step 7: Consider the window function

If the window is intended to be operational, ensure that you leave enough measurements for the opening mechanism. Consider the window type and the size of the opening before taking measurements.

Step 8: Check the level

Ensure that the window is levelled before taking measurements. Measure the distance from the bottom left corner to the top right corner and bottom right to top left. The measurements should be the same if the window is levelled.

Step 9: Double-check the measurements

Double-check all the measurements to ensure that they are correct. Remember, even small errors in measurements can influence the window’s fit.

Step 10: Account for allowances

When measuring for replacement windows, it is crucial to account for allowances, such as the gap between the new frame and the existing frame.

Step 11: Take a photo

Taking a photo of the window can be helpful when consulting with a window specialist or when ordering custom windows. A picture can give the specialist a visual representation of the window to provide accurate advice.

Step 12: Consult a professional

If you are unsure about the measurements or want to have a professional do the job, you can book a consultation with a window specialist or installer to guarantee accurate measurements.

Tips and tricks

Tip 1: Invest in quality measuring tools

Investing in quality measuring tools can significantly improve the accuracy of measurements. Tape measures and laser measuring devices can provide more precise measurements than traditional rulers or yardsticks.

Tip 2: Measure twice

Double-checking measurements can avoid costly mistakes and ensure a perfect fit.

Tip 3: Measure when the weather is favourable

Measuring during rainy or windy weather can be challenging and lead to inaccurate measurements. Plan to measure when the weather is calm and favourable.

Tip 4: Consider energy efficiency

When replacing windows, consider the energy efficiency of the new windows to maximise the savings on heating and cooling.

Tip 5: Consult with a window specialist

Consulting with a window specialist or installer can provide information on window materials, energy efficiency, and installation.

Tip 6: Keep a record of measurements

Keeping records of measurements can be helpful when ordering custom windows, ensuring accuracy and consistency.

Tip 7: Don’t cut corners

Avoid cutting corners during the measuring process, as it can lead to errors and unnecessary expenses.

Tip 8: Measure multiple times

If you are unsure about the measurements, measure multiple times to ensure that the measurements are consistent.

Tip 9: Consider the resale value

Replacing windows can improve a home’s resale value, so consider the aesthetic appeal and energy efficiency of the new windows.

Tip 10: Allow for ventilation

Consider the amount of ventilation the window provides before taking measurements. Proper ventilation can improve indoor air quality and reduce the risk of mould growth.

In conclusion, measuring a window may seem like a daunting task, but it is crucial for ensuring the perfect fit. Take the time to measure correctly and accurately, and consider consulting with a window specialist for custom windows or professional installation. Remember to account for allowances and energy efficiency during replacement, and keep a record of measurements for future reference. With these tips and tricks, you’ll be on your way to measuring windows like a pro!
