Window Area Calculator

Measuring the area of your window accurately is a crucial first step when you’re planning a renovation, replacing broken glass, or simply estimating the cost of a new window installation. At Window Repair Singapore, we’ve developed an easy-to-use Window Area Calculator to help you quickly calculate the square footage of your windows and get an estimated cost for your project. Whether you’re a homeowner, contractor, or interior designer, our tool is designed to simplify your measurement process with precision and clarity. This guide walks you through everything you need to know, from how the calculator works to why accurate window measurement is essential in Singapore’s climate and housing landscape.

🧮 What is a Window Area Calculator?

A Window Area Calculator is a digital tool that helps you determine the area of a window using simple dimensions, namely the height and width. It’s especially useful for estimating the cost of glass replacement, choosing window coverings, or understanding the scope of renovation work. In a densely populated urban setting like Singapore, where space optimization is critical, accurately measuring your window area can prevent costly mistakes.

Unlike manual calculations, the calculator on Window Repair Singapore offers instant results in various units (feet, inches, meters, or cm), along with a cost estimate if you input the price per square foot. This is ideal for residents in HDB flats, condos, and landed properties where window styles vary widely. From sliding windows to casement or full-height balcony windows, our calculator makes things easier and more accurate than ever.

🛠️ How to Use Our Window Area Calculator

Using our Window Area Calculator is incredibly straightforward, even if you have no technical background. We’ve designed the interface to be user-friendly, intuitive, and accessible across mobile and desktop devices. Whether you’re replacing a single window pane or measuring multiple units, the tool is flexible enough to handle all your needs.

📏 Step 1 – Measure Your Window Dimensions

Start by measuring the width and height of the window opening you want to calculate. Use a measuring tape and make sure you’re noting the inner edges of the window frame; this gives a more accurate representation of the glass area. For odd-shaped or custom windows, divide the frame into rectangles and calculate each one individually.

You can measure in centimeters, meters, inches, or feet, depending on your preference or your contractor’s specifications. Keep in mind that Singapore’s renovation industry mostly uses metric units, so cm or meters are often the most practical.

📐 Step 2 – Choose Your Units

After taking your measurements, input them into our calculator. You’ll find an option to select your preferred units. Whether you’ve measured in cm, meters, feet, or inches, our tool automatically converts them into square feet, the standard measurement used for quoting prices in Singapore’s home repair and renovation sector.

This flexibility ensures that no matter how you measure, the tool will adapt. If you’re using American measurement units or following specific architectural blueprints, there’s no need to do any manual conversions; we handle that for you.

🧠 Step 3 – Get Instant Area Calculation

Once your dimensions and units are entered, the calculator immediately shows the total area in square feet. This is crucial for estimating the amount of glass required, as well as cost estimation for replacement or repair.

If you already have a rough idea of your cost per square foot, for instance, SGD $10 or $15+, you can input this into the calculator to generate a real-time price estimate. This makes it easy to compare quotes or prepare a preliminary budget before you call for an on-site inspection.

🔍 Why Accurately Measuring Window Area Matters

Accurate window measurements are more than just numbers; they directly influence your budget, design outcome, energy efficiency, and even safety. If your calculations are off, you risk ordering the wrong size of glass or frames, which can delay your project and incur extra costs.

At Window Repair Singapore, we often encounter clients who underestimate the importance of precision. Whether you’re installing double-glazed windows, laminated safety glass, or solar-reflective panes, the dimensions must be exact. Accurate area measurement also helps you avoid wastage and reduce your carbon footprint by only using what’s needed.

🧱 Common Window Sizes in Singapore

Singapore homes come in a variety of formats: HDB flats, condominiums, landed houses, and even commercial buildings, each with distinct window configurations. Understanding the common window sizes can help guide your measurements:

🪟 Sliding Windows

Typical for HDB and condo living rooms and bedrooms, sliding windows often span 100 cm to 180 cm in width and 90 cm to 150 cm in height. They’re ideal for ventilation and easy to operate, but require accurate measurement due to overlapping panels.

🪟 Casement Windows

These are side-hinged and open outward. Commonly found in kitchens and bathrooms, they range from 60 cm to 100 cm wide and 80 cm to 140 cm high. They often include grilles, which must also be considered in measurement.

🪟 Louver Windows

Perfect for areas needing ventilation like toilets or storerooms, louver windows typically measure around 40 cm to 70 cm wide and 60 cm to 120 cm high. They’re segmented, so consider the entire structure when calculating area.

🪟 Full-Height or Balcony Windows

Popular in modern condos, these run floor-to-ceiling, often 2.4 to 3 meters in height and 1.5 to 2 meters in width. Due to their size, the cost per square foot plays a major role in budgeting.
