Does my monstera need a bigger pot?

[Baconking]

My Monstera is growing lovely, 2/3 new stems last year and a couple already this year.
However they spread out so much it looks so untidy and is difficult to turn as the leaves end up squashed against a wall.

I've added photos, is it because I need to move to a larger pot? I don't really like swapping plants around as I'm scared I'll kill it...

Let it dry a little bit then tip it out of the pot and have a look. If it's mostly root then repot but only go up a pot size or two. If there's still lots of dirt without visible roots you can probably leave it for now. It might need staking.

As above, have a look and see if it's pot bound and if not it should be fine. I would suggest getting a moss or coco coir pole and staking it though. It'll help give it a bit more shape

Thank you. Novice plant owner here, but now have 5 live ones!

Will order a stake and check the root in a few days (just watered).

Looks like you possibly have 2 plants in that pot OP. Monstera are vining plants (they want something to grow up) so you'll need to give them some support too stop them growing sideways. A moss pole is ideal but a stake will work also.
