https://imgur.com/a/WJSqxKj Sorry I'm sure this is a silly question but I'm a bit confused. The drywall in my house seems to thin to be 5/8 but too thick to be 1/2. It's knockdown textured so I'm not sure if that adds depth. I'd appreciate any advice! Edit: after cleaning it up and scabbing some framing, it's 1/2! A few spots with a decent amount of lippage but overall not that bad!

Looks like 1/2" to me.

If you want to be more sure, take a 1/2 and 5/8 open end wrenches and see which one sliders over it and fits snugly.

Oh great idea! I'm thinking it is 1/2. It's just thickened by the compound and texture/paint. I'll try your tip.

Yea- paint and finishing adds more than you’d think.

I think its half inch, and is just frayed from the cut

Clearly drywall was too cheap looking so they made your walls out of 9/16 drop ceiling tiles.

I literally just dealt with this exact scenario.

It's 1/2. The knockdown, primer and paint add to the thickness so if you were to peel all that off it would measure 1/2

I removed a tub in our bathroom that was attached straight to studs so I need to patch where it was. I guess I'll just do 1/2 and add a skim coat(s) till it's flush with existing

Generally most of the sheetrock in your house is half inch. The wall inside and the ceiling of your garage are 5/8" for fire resistance.

I'm in camp 1/2. Because if you zoom in the drywall is not tight against the wood. That's your 1/16 difference

Reddit brother. The board is 5/8 thick but it’s cut before the stud so the board has a slight bend. If you’re going to complete this job use 1/2 drywall because you can always add on with plaster to make a nice joint. If you buy 5/8 you MIGHT get a bump…….. but you have 7/8 to play so you can just go light on the compound. Either way you have play room, good luck sincerely a framing and drywall contractor

Thanks man. I'll just do 1/2 and skim coat it flush with the existing. Removed a tub from our bathroom that was attached straight to studs so I just need to patch up where it was.

Def 9/16” Must’ve been a custom job.

Crazy how there's even a tape measure on it, and still people saying it's anything but 9/16"

1/2 “…the mud at that joint makes it look thicker

If it’s on a wall, it’s like 1/2” with just a lot of skim coat and texture.

Having said that, if you’re trying to match the nearly 1” depth, you could buy 5/8” to help save you time skim coating to build up the thickness.

I say that's 5/8 looks like you got mold so cut to halfway through the next stud so both sheets of drywall can have a mounting point.

That’s hire a pro size. If you can’t read a tape you’re in over your head.

Fellas, this is half inch rock. The tape hook isn't static, and moves a little. Push it in like this and it measures too long. In this case, by less than a 16th. The 5/8ths line is very far away. If you'd measure it by hooking on the back, it would measure a perfect half.

The slop in the tape hook is designed to be the thickness of the hook, so it can be accurate for both push and pull measurements.

I’m not going to say that I was “today years old” when I learned why the end of the tape moves like that, but I will admit that I was “embarrassingly old and should have known better” years old when I did.

The end of a tape measure is supposed to move. It is designed to move exactly the thickness of the tab so that you can measure from either side of it.

ThisSubHasNoMods t1_jecjfz5 wrote

The end moves to compensate for the thickness of the metal hook at the end. Op measured correctly.

Kind of. He measured against the stud and you can see a small gap. If he hooks the back of the drywall with the tape it'll likely land on the 1/2" mark pretty cleanly.

jet_heller t1_jecskuj wrote

Yea. You can see the sheet isn't entirely against the stud and it could be hooked. That's the correct way to measure it in this instance.

New2ThisThrowaway t1_jecjmm1 wrote

This isn't true for all tapes. It should measure correct when used this way, but the ends are notorious for being inaccurate.

You can see the inaccuracy in the photo. Use a photo editor or a post-it on your screen and grab 1/2 inch from further down the tape. Move it down to the end and you'll see your 1/2 inch reference line up with 9/16th.

Summary: it's 1/2 inch board. The tape measure is off by a 16th, like you said.

That’s called perspective. Things closer look bigger… welcome to the Renaissance!

Right? I’m looking at this like, are we all looking at the same tape measure? It’s 1/2” rock.

Call off the detectives. It’s 1/2” rock.

Hook the tape on the back of the sheet and pull it towards you, and it will measure 1/2”.

That's 5/8". It's everything else slapped on top that adds the depth.

Looks like 5/8 with a hefty layer of mud and paint

Looks like 5/8” keep in mind that drywall thins a bit at the edge.

It’s cut so it’s not the factory edge anymore.
