For ceiling in basement do you need the ceiling drywall to eliminate sag or is regular ultralight drywall ok?

Either is okay. I've never experienced sag from regular ultra light drywall. I believe it's just another marketing thing.
Hi this is Matt with Property Inspired Construction
Dependent on the joist spacing both would be fine, we always try to get the biggest sheets we can into a basement on the ceiling to eliminate un needed joints, so when using longer sheets ceiling board or even 5/8 is much nicer to work with.
Ceiling board and 5/8 will give some minor deadening qualities for acoustics too, ultralight basically nothing as is much less dense.
Ultimately they all finish the same we use ceiling board generally because we are dealing with 12 & 14 ft sheets as much as possible.

Hi Jeff,
If you have 16 inch on center you can use the 1/2" drywall but if you have 19" or 24" centers then you should use the nonsag 1/2" drywall but they only come in 12 to 14'lengths.

Hi Jeff, this is Jeff here. It is fine to use ultralight half-inch drywall on ceilings in the basement. However I prefer 5/8 fire-rated drywall on basement ceilings it's always better to be safe than sorry.
The guys have a point on the ultralight for sound deadening it wont do as much but as far as sagging it is more dependent on the joist spacing, if your at 16" it should not be a problem.
