How often do you all weigh yourself?

Daily, but log weekly on my spreadsheet.
The daily weights I log on a free app called Libra, it's good because over time it shows your trend and stops me freaking out over those unexpected, sudden gains and also gives a bit of perspective to the same in losses!

Once a week.

Don't worry too much about it, weighing is only one measure of progress, you can't really get it wrong as such!
Main thing is to find what works for you.
Some will weigh daily, others weekly or Monthly, and some not at all!
I did weekly for a long time, then went to daily and didn't like it to start with, but I wouldn't go back to just weekly now, personally.

I weigh in one a week (always a Friday morning) but I also feel tempted to weigh in sooner. I never do though - I like to be surprised

I weigh daily. For me personally, I wanted to weigh daily for a while because I had read that fluctuations were normal, yet for my whole life I have gotten depressed over any gains on the scales. I needed break that mentality so thought that weighing in daily and tracking it on MFP would help me to see slight gains as part of the process. I also learned to back myself - if I'm doing the right things with food and exercise then my weight trends downwards over time. It is not linear.

About once a month. Especially as a woman, my weight fluctuates a lot, so I don't waste time doing daily/weekly weigh-ins. My exercise regimen consists of challenges. I exercise at the same time everyday, but to avoid boredom, I change the TYPE of exercise every couple weeks or so. Therefore, I weigh myself at the end of each of these exercise blocks. Through this method, I've been losing weight like clockwork, as expected (4-8 lbs a month). Science doesn't lie. It really is about calories in vs calories out. I eat within 1200 calories, and I always exercise, even if it means doing yoga or tai chi on a rest day.

My goal is to weigh in once a week with my naturopath who's keeping an eye on me I used to weigh in daily and it was so hard on my emotional health. It could make or break my day and my self-esteem and really skewed by sense of how I was doing. I know that weekly weigh ins could set me up to - if I happen to land on a day where I'm up unexpectedly - but I think it's healthier for my mental game.

Every day..but I also know that weight fluctuates depending on a lot of factors so that is not the most accurate way. Most peeps will tell you once a week and look at the trend is the best way, I am certain it is, just not what I personally do cause I like to be able to make course corrections on a daily basis. Silly..yeah maybe..but it works for me

Every day, so that I can log it in Libra. This teaches me about daily fluctuations. I only log when I've been at the lower weight for a couple of days

Once a week... on mondays (i like weighing on monday cause it keeps me on track over the weekend)

I try to stick to once a week (or less). If I do it more than that it's to satisfy curiosity but is not particularly helpful.

I weigh when I can every 4 days or so. I try not to do it too much because for me, it's a bit depressing everyday when I gained weight one day and then the next dropped. lol once I get my own scale I will probably weigh everyday again though, bc I'm trying to have more "observations" verses "judgments" on myself, it gives me an idea of what my body is doing. ie retaining water, the weight of food not digested through etc. but it would be up to you and how you feel I guess. Like if I ate a lot one day, then I wont weigh myself the next because I know the result - no weight loss. So it's entirely up to you.

Daily and try not to focus on the day-to-day fluctuations, but rather the trendline*
