How big? My go to method for little stuff (<1/4") is to get a wood dowel of approximately the right size, and thread it in. Measure the ID (minor diameter), count the threads, buy one and try it.
Bigger ones, where I can get a thread gauge inside, then use calipers to measure the minor diameter, and look it up online.

You mean they, their or them threads?

No, those terms are unacceptable. You are about two weeks behind the times. They are now called birthing threads or threads with ovaries.
identify in what way?
To the OP, for small threads you pretty much have to have a fastener that fits the hole, a thread tap, thread chaser, or a thread checker, because a leaf style flip out thread gage won't fit down into small diameter threaded holes. RTM's wood dowel idea sounds like a good one as well, I'll have to try that myself in the future.
For larger sized holes when none of the aforementioned options work, I have a spare triangle shaped PEC Tool 5651 thread gage that I took apart and put all the individual leaves onto a small ring of ball chain. That way a single thread leaf can be removed from the chain or used on the chain without the triangular shaped holder getting in my way. You can see the before and after versions within the red circle in my attached pic. I use a digital vernier caliper or a small hole ball gage to get the minor diameter measurement I need after the threads have been determined.

I start with pitch gauges (leaf style.)
If it matches 1.25mm, or 24 tpi pitch, the options narrow quickly, since there are only so many commonly made thread pitches for a given size.
Learn how to do the math to determine minor diameter using the o.d. and thread pitch.
If you have access to bolts, try them.

What about the threads that were manufactured as external threads but are now have been redefined as internal threads?
That dynamic does exist, but it falls outside the scope of this thread. See what I did there?
As a side note, I would like to apologize in advance for my previous post. The correct terminology has changed once again, so I don't want others reading this thread to think of me as being out of touch with reality. The correct term is now "threads that menstruate".

Looks like a useful tool. But the name is too skewed toward the male. I mean "nut" and "bolt" thread checker. It even looks like a "pearl necklace". Guys love to give those to women. I'm sure this will offend many.
From now on the fastener formerly known as a nut will be called a ******
. The ****** will have the female threads on the inside and the bolt with have the male threads on the outside.bugnut

Measure as close as possible to the inside diameter. If you lack calipers the shank (dull/chuck) end of a drill inserted into the hole can get you close to an inside diameter. Then google the inside diameter and pick the closest size, usually then the choice is either fine or coarse thread.

That's insensitive to threads in menopause. Now take you vile male and cis-thread-gender elsewhere.

You know it’s strange that I never really considered the ****** connotation of male and female threads and plugs. etc. etc.

A female thread is always internal to a part, as opposed to a male thread which is external. Don't they teach anything useful in the schools the last 50 years?
They stopped teaching interconnection course in schools years ago.

I use one of these to check threads, both male and female. SAE and Metric, coarse and fine up to 1/2-20.

I should clarify, my method is for something non standard which does not line up with my tool like Designer posted just above, and others. I refurbish lots of vintage tools which use oddball threads.

I absolutely love them. Male on one side and female on the other. If you think they are pricey, consider all the trip to the hardware store!

It is not acceptable for you to identify a thread as female, but (for the time being) it is acceptable to ask the thread in a very non-judgmental way how it identifies today.
Is twisted acceptable?

Application is a big part. 10mm head? M6x1. Looks like 5/16 diameter on something metric? M8x1.25. Looks abnormally thin? M8x1. Thread chasers are my preference. 2 tools in one, identify and repair. Best of all if you have a fastener and its pairing threads, you can check whichever is easier to get at.

So they are bisexual now? Not that there is anything wrong with that. Or is it now officially trans gender screw checkers now? I can’t keep the terms straight anymore.I used these thread checkers: https://www.amazon.com/dp/B06ZYD4SS8/?tag=atomicindus08-20

Well a female thread might include lots of gossip about her friends, oh wait, that’s not the kind of thread you meant.
I have several thread pitch gauges. Usually with SAE I can just look at a nut and tell what size it is. On metric, I use my thread pitch gauge and measure the ID with a pair of calipers then add the thread pitch to get the right size.

I wonder if one could screw in a piece of soft plastic or wax and measure the thread after it was removed. Inserting another bolt makes sense. But sometimes it is hard to tell after the thread has been damaged....?
