Ladies - How many pounds for YOU to lose a pants size?

I'm 5'1" From 225 to 193 I went down from a 20 to a 16, but I'm back up to 203 and still in the 16s so I probably could have dropped sooner than I did.

Thanks for that info, tomteboda. I always suspected that as sizes get larger the difference between each size is greater. In the very small sizes (less than a 6) there isn't much difference and 5 lbs can easily push you up a size. This might lead to more frustration for people in the larger sizes because it seems you aren't moving ahead as much as you are! I found as I gained weight it took more pounds to go up a size (which has the other bad effect of helping disguise how much your weight is changing).
Another interesting topic is, how many bra cup sizes did you go up? I've gone up 4 and the expense of buying new bras every time I gain weight is actually a big issue. This is the one item of clothing least forgiving of weight gain, in my case!

I'm 5'10 and its about 20-25 pounds per pants size. I've never been below a 14 as an adult, even when I weighed 160-ish ( within "normal" BMI).

Shirts are different, though I need at least a L for shoulder width and sleeve length. I lose from above the waist first, and very noticeably.

I'm 5'6" and currently weigh about 170. I've lost 45 lbs, so started at 215ish.

At my highest, I was fooling myself into thinking I wore a size 16. It was probably more like an 18.

The pants I'm wearing right now are a 12 and they fit great.

So, 3 sizes in 45 lbs. I guess that's about what everyone else has said - 15 lbs to a size...

I lost 50 lbs and went from a 16 to probably a size 10 now (depending on brand). I'm 5'10".

I still have to remember not to grab size XL in everything (and hope it fits).

Even though I've lost over 15 pounds, I haven't gone down in pants size yet. I AM down a cup size, though. It's an unfair combination!

I don't have just one size listed because at each weight, I tried on different pants from different brands and the ones that fit all had different sizes.
Stats: 5'2" on a good day and maintaining a 108-114 lb range with 110 being the UGW.
Start: 168 lbs, US size 14-16
During: 130-ish lbs, US size 7-9
Current: 110lbs, US size 0-5. Yes. All pants I own right now are in this range of sizes. Shopping for bottoms takes forever. I never know what's going to fit. Maybe it's because I don't go shopping enough?

I've gone from size 22 and 236 lbs to size 12 (well - I'm in between 10 & 12 so we'll call it 12 still) and 171 lbs. 65 lbs gone, and 5 pants sizes...I'd say about 12 - 15 lbs per size!

10lbs for me to go from 12 to 10

I was 190 lb, size 12 pants
I lost 32 lb and I am now size 8
So 8 lbs per size?
It has a lot to do with height, body shape, etc.
I am 5 ft 6 in.

I have lost 40 pounds as of today, and I am currently a size 10 UK/ 6 US.

I can fit into a snug UK 8/ US 4 for tops but not bottoms.

I'm not exactly sure. I started off at 169 pounds and a size 11 in most things, 13 in a couple (I'm 5'5.5"). Definitely could NOT get even a 9 past my thighs. Tops in juniors were large, dresses in misses (never bought Juniors dresses) were 10. I now range 146 to 149 and easily fit into a size 3 for most things, and Juniors size small tops. I haven't bought a dress recently, so idk.

So to answer the question, I didn't really go shopping until the 11s absolutely would not do for me anymore, as in falling even with a belt, but 4 sizes over roughly 20 pounds is 5 pounds a size???? That seems really weird from the general consensus of 10-15 pounds per size though. I will say that when trying on pants, I'll get a 3 and a 5. I often have to pull them on and off to see which I like best because they are so similar. The distinguishing factor is that the 5 is slightly too big in the waist, that's it. When I was in an 11, a 9 wouldnt come past my thighs and a 13 would usually hang off of me. I think what someone said early about bigger sizes having bigger differences is very true. If I'd kept a log, it would probably look more like: 1st 10 pounds, size 9. Next 5 pounds, size 7. Next 3 pounds, size 5. Next 2 pounds, size 3.

I never paid attention to how many pounds I lost before going down a size. I have lost 70 pounds in just over a year. I started in a size 18(probably should have been wearing a 20). I now wear a 10/12. It all depends on who makes the pants and the cut.

About 20 pounds for me. I lose most of my weight in my upper body.

Any weight I gain goes to my bottom half. I wear a Junior's size 6 now. If I lose 4 more pounds I can wear my size 5's.
