How do you measure a caravan window?

To measure a caravan window properly, follow these simple tips: 

  1. We recommend that you measure the width and height in three different points and take the smallest of the three measurements as the right ones. Add one cm to the width and height measurement.
  1. It is also convenient to measure the diagonals, this will give us an idea of ​​the possible miss-square of the gap. Make sure to always measure from the surface of the jambs or frame, not from the short extensions that hold the window in place.
  1. Take into account the covering around the caravan window. If the gap is already occupied by an old window, you will see a plastic, aluminium, or wood cover attached to the vertical sides. This will be removed before installing the replacement window. 

Thus, measure the width of the canopy and add it to the width of the window opening. If you can’t access the cover to measure it, use a measurement of about 1.25 centimetres.

  1. To measure the depth between the two stops that extend in front of the window frame. Try to measure the shortest point. If you can’t open the window, measure the depth on each side and add up the results (if for any reason you can’t access the outside of the window, you can get an approximate measurement by measuring the depth on the inside side and multiplying it by two).
  1. Confirm that the window opening is rectangular. Measure the window opening from the top left to the bottom right and record the measurement. Measure the distance of the opposite angles (upper right to lower left) and compare the result with the first measurement. 

If the two measurements are not the same, the window opening is neither rectangular nor square. In this case, it is convenient that you inform the manufacturer or installer of the new window.

More tips:

  • If you can, use a metal tape measure. You will gain precision.
  • You must take the measurements of the windows in millimetres. In this way, you will obtain the most exact measurement possible.
  • Take into account the position of the window handles or any other obstacles that may be present.
  • Also, measure the height of the sill (the wall below the window opening). That is the distance between the floor of the room and the windowsill. This measure will allow the manufacturer to position the handle of the new window in relation to the ground so that opening the window is as comfortable as possible.
  • You should also measure the interior hole of the window. When you provide these measurements, add 1 cm to both the height and the width.

Take measurements from the surface of the jambs, not from the weatherstripping or rods the window that goes to change.
