Weighing in clothes?

No. It gives you an idea of how much you've lost. If you reallyyyy want to be super accurate though, substract about a pound.

Not an exact science sadly lol. all dependent on the style of clothing (Hoodie instead of tank top, sweatshirt or t-shirt, sweatpants or leggings or shorts), fabric
(cotton, lycra, Corduroy lol), shoe type (light weight running shoes, combat boots). Usual number can be anywhere from 3-6lbs depending on your fashion sense :-). Hope this helps.

Let me answer your question first - it depends on the clothes. Usually they're ~3 lbs (including shoes), but I would NOT exclude them.

But to get the most precision, the key is consistency... if you don't have your own scale - make sure you are wearing the same 'amount' of clothes. try to make it around the same time of day... and since you are doing it at the gym, make sure it is either before OR after your workout... don't flip-flop.

Most people prefer morning weigh-ins, because a lot less factors come into play( water retention throughout the day, amount eaten in a day, calories consumed prior to weighin) but that is just preference.

Being consistent with how/when you weigh in will give you the best estimation of your loss.

**EDIT - altered 1st line for clarity

if you're weighing yourself at the gym, you've probably had at least a drink that day, even if not food! You may not realise, but a big glass of water weighs 1lb!

As you seem interested in accuracy, forget the gym scales and buy some of your own so you can weigh yourself first thing in the morning.

I find the most accurate measurement is in the morning, just after I wake up, before I drink anything, naked.

The variation throughout the day is up to 10 pounds, after I have eaten, drank coffee, put on clothing, make up, hair care products. So invest in a home scale, I personally find it helpful.

yeah you'll weigh more. but its not about the actual number, this is what i tell my clients - im a PT. as long as you are wering pretty much the same sort of thing you'll keeping variable similar. so you'll see a progress and loss. if youre intrested purely in the number, buy a pair of scales for at home and go nakey for weighing! i put my work clothes in a bag (not including trainers) and i was wering 2.5 lgs (about 5lbs) of clothing, that was a fleece, tracksuits 2 tops, a bra a croptop socks, undies and leggins so, yeah there was a huge differnce lol!! but yeah dont stress just wear the same sorta thing and do it that way

It really depends on how heavy your clothes are. But since it's at the gym it's probably around a pound. If you wanna be more accurate you could take your shoes off. I still only weigh myself (unless it's at the doctors) right in the morning after I go to the bathroom, before I've eaten anything, and without my clothes. That way you only get your body weight. Not your food, water, or clothes weight.

I weigh myself at work. I take off my shoes, but I still have a full outfit on. I just subtract 1lb or so.

I strut around the gym naked before weigh in. It lets everyone know that I am about to weigh in.

fully clothed, the weight is up to five pounds heavier for me.

Bring the exact outfit as you are wearing, or close as possible, add shoes to it, just a bundle of clothes.
Weigh yourself with shoes.
Add shoes to the bundle of clothes.
Subtract for your weight.

Now you know how much those clothes weigh, and can do that in the future.

But for consistency, what others have said about time of day is much bigger influence than that type of accuracy.

Does knowing weight X is more accurate than Y by 2.6 lbs matter, when the glass of water you may or may not have had weighs 1 lb, or extra sodium in lunch retained 2 lbs of water?

If you buy a simple scale for home, stand on it several times at store to confirm it is consistent.

If you are weighing at the gym first thing in morning, day after rest day, then that is valid enough, weigh the clothes to subtract.

I like to be consistent so I weight myself naked in the morning after I've used the bathroom and before I eat or drink anything.

Truthfully for me. I don't count or discount clothing. I'm more caring about a difference in weight, so just try to wear consistant types of workout clothes so that instead of taring at 0 you are at 2 or 5 - but that won't change the number of pounds lost... Plus once finally down at the goal weight, generally that 2 or 5 isn't quite so important anymore.

If you have a digital scale, you can weigh yourself multiple times and the weight will probably change. They also say that time of day, hormones, stress, salt, water, etc - will also cause a more dramatic increase/decrease of weight over or within a single day, than any amount we may have actually lost for that day. So basically weight fluctuates anyway - I wouldn't worry too much about it. Go with what you feel is comfortable.

I do measure and prefer inches over a scale though.

When I was in the Marine Corps back in the 90's, we subtracted eight pounds when weighing in our camoflauge uniform with combat boots on.
I would imagine that clothes themselves weigh only a pound or two, and the determining factor is how much your shoes weigh. They can add as much as five pounds on their own before factoring in clothes as well.
It's very unrealistic to suggest that you wear the exact same thing when weighing yourself at some location away from home, as people will notice that you always wear the same thing, and begin to think you're some kind of weirdo.
But, you likely wear the same type of clothing to that gym. So simply take your shoes off for the brief moment that you're weighing yourself, and then subtract about a pound off your measurment for just your clothing.

Best of luck to you!
