Measuring Guide: Corner Windows and Bay Windows

Bay windows and corner windows are two of the most common window types found in Australian homes. If you have either of these two window types, then measuring up for new window treatments can take a few extra steps. However, it doesn't have to be tricky, use this simple measuring guide to ensure you get the perfect fit, every time. Just remember, measure twice and order once!

Corner Window

Whether you are mounting window coverings for corner windows on the inside or outside of the architrave, one blind can run the full length and the second blind will butt up against the first blind to prevent light leakage in the corners. Follow these simple instructions and illustrations below, on how to measure for corner windows, both inside and outside mount.

1. Start by measuring the width of one window by taking the measurement along the front of the window opening (follow the wall). For inside mount, measure from the inside of the architrave to the corner and for outside mount, measure from outside the architrave to the corner. Then, repeat this process with the second window.
2. Next, measure the height in three places (left, middle and right). For inside mount, measure from inside the architrave to the bottom and for outside mount, measure from the top of the architrave to the bottom. Do this for both windows to ensure you are getting the accurate height measurement for each individual window.
3. For inside mount, also measure the depth of the window reveal. Measure from the front of the architrave to the window. Be sure to take note of any window handles or locks. If you have handles or locks that will obstruct the blind, measure from the front of the architrave to the handle or lock. Ensure you provide Veneta with the depth measurement.

Note: Provide the height, depth and smallest width measurements (to the millimetre) and Veneta will calculate the size of each blind and take the relevant deductions depending on your window treatment type.

Now let’s take a look at how to measure for a bay window. There are two common bay window types; the standard bay window and the box bay window.

Bay Window

When mounting window coverings for bay windows on the inside or outside of the architrave, the blinds will butt up against each other to ensure the smallest gap possible between the blinds. Follow these simple instructions and illustrations below, on how to measure for bay windows, both inside and outside mount.

1. Start by measuring the width of each window by taking the measurement along the front of the window opening (follow the wall). For inside mount, measure from the inside of the architrave to the corner and for outside mount, measure from outside the architrave to the corner.
2. Next, measure the height of each individual window in three places (left, middle and right), from inside the architrave to the bottom for inside mount and for outside mount, measure from the top of the architrave to the bottom. Do this for all windows to ensure you are getting the accurate height measurement for each individual window.
3. For inside mount, also measure the depth of the window reveal. Measure from the front of the architrave to the window. Be sure to take note of any window handles or locks. If you have handles or locks that will obstruct the blind, measure from the front of the architrave to the handle or lock. Ensure you provide Veneta with the depth measurement.

Note: Provide the height, depth and smallest width measurements (to the millimetre) and Veneta will calculate the size of each blind and take the relevant deductions depending on your window treatment type.

Box Bay Window

For box bay windows, one blind will run the full width and the two other blinds will run from one side of the architrave to butt up against the full width blind. Follow these simple instructions and illustrations below on how to measure for box bay windows.

1. Start by measuring the width of the left and right windows. For inside mount, measure from inside the architrave to the corner or for outside mount, from outside the architrave to the corner. Then measure the centre window from corner to corner. For width measurements, ensure you are measuring from the front of the window opening by following the wall.
2. Lastly, measure the height of each window from inside the architrave to the bottom for inside mount or for outside mount, from top of the architrave to the bottom. Do this for each window to ensure you are getting the accurate measurement for the individual windows.
3. For inside mount, also measure the depth of the window reveal. Measure from the front of the architrave to the window. Be sure to take note of any window handles or locks. If you have handles or locks that will obstruct the blind, measure from the front of the architrave to the handle or lock. Ensure you provide Veneta with the depth measurement.

Important Notes:

- No matter the window treatment type you choose, if you have a corner window or bay windows, there will be a gap between the blinds. That gap size will be determined by the type of window treatment you choose. Keep this in mind when you are deciding on the best window treatment for your windows.

- For a corner windows and box bay windows, one window treatment will offer full coverage. You will need to decide which window this will be. If you live on a main road or the windows are in a bedroom, choose the window that faces the road or the main window that has the most exposure to outside.

- For both inside and outside mount, always take your measurements along the front of the window opening, following the wall.

Before you get started, grab out a piece of paper, a pencil and a tape measure. Be sure to write down the measurements you take. This will ensure that when it comes time to order, that you have the accurate measurements and your new blinds will arrive at the correct sizes.
