How much can you cut off of a door?
About 1.25″. You can cut them down and glue in a slug. If you are bored you can clean off the cut out section and glue it in. You will void your warranty either way.
Can you trim the side of a door?

How Much Can You Trim off a Hollow Core Door? Removing an inch or so from a hollow core door to allow for a thicker carpet, misread tape measure or wonky doorframe will be fine. However, cut off too much – roughly over 2 inches – and you may notice that the edge of the door is no longer solid.
How do you shorten a door without removing it?
To sand the bottom of a door without removing it, put the sandpaper on the floor, grit side up, and pull the door back and forth across it. Planing is usually the last resort, since it will mean touching up the planed area with a sealer or finish to match the door. A rasp-type plane will often do the best job.
What tool do I need to shave a door?
You can also use a hand-held power planer or a hand-held manual block plane to shave down a door. These two tools require more skill. If you’re experienced with them use them if you want. But if you’ve never used them you can damage the door.
