Measuring up for new internal doors

Welsh_Totster

I'm about to buy new doors for inside the house, what's the best way to measure up to make sure I get the right size? Do I measure the inside of the frame or the door that's currently in situ? I'm door clueless as you can tell! Ta

I would measure the inside of the frame, they will probaby be either 30" or 27" width,the 27" normally a bathroom or toilet door.
the heights should be 78" .
Also measure the door width , measure the rebate depth on the frame ,internal doors are normally 39mm ,external are 45mm

It is unlikely that the doors that you buy will fit without some alteration. Just a thought to bear in mind. Some people think that you can just go and buy a new door which will fit the opening. This may be the case occasionally, but it is much more usual for the new door to require planing to size.

Respectfully, standard Internal doors (not fire rated) are 35mm deep and externals are 44mm
