Do you want to replace your current doors? It’s surprisingly easy to make a costly error by ordering the incorrect size.

If the seller agrees to take the door back, you may still have to cover shipping charges. Not to mention the added hassle of tracking down a replacement door and footing the bill for shipping it again.

Finding out what size you need is as easy as following these instructions.

Honesty is essential. Unless you’re replacing the doors leaf and frame altogether, you should check that the frame you’re using is perfectly straight and level. You may make sure of this by taking diagonal measurements from corner to corner in both directions. More than a 5mm discrepancy between them indicates the need for professional frame adjustment or replacement.

Check the frame’s condition as well. A door’s weight can reach 50 kg, thus it’s imperative that it holds up well. It can be more cost-effective to replace the entire door assembly if there is significant damage (frame and doors).

Determine the following to determine the appropriate doors size:
Door leaf dimensions
Door Handle Locations
Dimensions of door frames

Door leaf measurements

Take numerous readings of the doors dimensions from various spots and write down the averages. When there is a wide range of possible outcomes, it is best to go with the bigger ones. A oak doors lincolnshire that is too large may usually be trimmed down a bit, but a door that is too small cannot have anything added to it.

Where to find the right measuring tools

Handles, locks, latches, and hinges, among other hardware, are not typically included with a door. You can possibly reuse the current fixtures if they are still in good shape. If not, you’ll need to acquire the hardware separately and adjust it to the dimensions of the new door before installing it.

Take careful measurements of where the former hinges, handle, and closing mechanism were attached to the frame.

Run the tape from the existing door’s top to the top of each hinge to get an exact measurement (there will probably be at least three). Put the tape flush against the door’s surface and make sure it stays straight.

The size of the hinges and the hinge reveal must also be measured (the distance between the edge of the hinge and the edge of the door).

Next, you’ll need to determine where the lock set (the latching mechanism) is located. If the latch is not precisely aligned with the appropriate hollow in the frame, the door may not close properly. If you want to know how far the lock set is from the doors newbury side or top, you need to take measurements.

Find out what dimensions you need to have the door frame at

Make sure you’re measuring the door frame itself and not the jamb or the trim around it. Door stops and architrave (or other wall trim) are standard fixtures.

Determine the frame’s width and height by measuring it from multiple angles. If there is a discrepancy in the numbers, use the smaller ones. In order to prevent the door from scraping, it is best to work from the top of the carpet down. This should be taken into account if installing new flooring.

Only the distance from the front edge of the door post to the front edge of the door stop needs to be measured in order to determine the depth (or thickness) of the frame. Leave off any wall moulding that is attached.


If you have all the dimensions, you can probably find a stock door that will work. In most cases, wooden doors can be trimmed to fit, but this is not always the case, so be sure to verify this before making a purchase.

The need for a custom-made door becomes more plausible if you discover that your frame is not a standard size. This method is more expensive but guarantees a snug fit.
