Can you trim down architrave for a door frame?

I need to replace 45mm-wide architrave on some internal doors.

I can’t find much architrave of that width that I like. Is it possible — or even advisable —to buy wider-than-needed architrave and trim it down without compromising anything?

Yes you can. In most cases I'd say it might look off, but with rectangular section archis or quarter round (fingernail) architrave so long as it covers the gap between the casing and the wall you'll be OK. I feel it needs to be consistent throughout the building, though, so if you do one doorway you need to do them all. Ripping down profiled archis often doesn't look good

Great, thanks @JobAndKnock

@foxhole It’s not possible to go with wider architrave because at 45mm it runs right up against the wall on one side of most of my doors.
