To calculate blind size, measure the width and height of the window, then add 2 cm (or 2 inches) to both the width and height measurements. This ensures the blinds fully cover the window area for proper fit and coverage.

The **Blind Size Calculator** is a handy tool that helps you measure the correct size for window blinds. By simply entering the window’s width and height, the calculator ensures you get the right blind dimensions for a perfect fit. It’s ideal for both standard and custom-sized blinds.

**Formula:**

To calculate the size of your blinds, use the formula:

$BW = WW + 2 \quad \text{and} \quad BH = WH + 2$

Where:

**BW**= Blind Width (in centimeters or inches)**BH**= Blind Height (in centimeters or inches)**WW**= Window Width**WH**= Window Height

Variable | Description |
---|---|

BW | Blind Width |

BH | Blind Height |

WW | Window Width |

WH | Window Height |

**Example Calculation:**

Let’s assume the **Window Width (WW)** is 100 cm and the **Window Height (WH)** is 150 cm.

Using the formula:

$BW = 100 + 2 = 102 \, \text{cm}$

So, the blind size needed is **102 cm width** and **152 cm height**.

Step | Calculation | Result |
---|---|---|

1 | Add 2 cm to the Window Width | $100 + 2 = 102$ cm |

2 | Add 2 cm to the Window Height | $150 + 2 = 152$ cm |

**What is Blind Size Calculator ?**

A **Blind Size Calculator** helps determine the correct size of window blinds needed for a given window. To calculate blind size for inside mount blinds, measure the width and height of the window frame. For **width**, take three measurements (top, middle, bottom), and use the smallest one.

For **height**, measure the left, center, and right sides of the window, and use the longest measurement. If you’re mounting the blinds outside the window frame, add around 3 inches to both width and height to ensure full coverage.

For example, if your window is **35 inches wide**, you would select blinds slightly smaller than this width for an inside mount, allowing the blinds to fit within the frame. The **window blind size chart** helps you find standard sizes based on your measurements.

There are also online tools like **blind size calculator in cm** or **blind size calculator in inches** to make these conversions easier, depending on your preferred units. Using a **roller blind size calculator** or a **blind calculator app** ensures accurate measurements and helps select the right product, whether for standard or custom-sized windows.

For specific blinds like roller or Venetian blinds, the same methods apply, and using a **window blind size calculator** can assist in finding the perfect fit for any window.
