Honestly, as PPs have said, I'm really not sure that a flat weight measurement is really relevant. I'm 5 ft 2 (used to be 5ft 3....😮) and would have guessed you at about 13 stone. You're curvy but not 'fat' looking. But I think weight is a really individual thing.
I always used to be a very small build, and never weighed much. I have tiny wrists and ankles etc. My heaviest was in my teens at 8 stone 3 but I look back at the photos and I wasn't anything more than slightly rounded. But I lost a stone as soon as I left school and was never more than 6 1/2 to 7 1/2 stone after that, until middle age. But I wasn't thin, I always had back fat and spare tyres. (Not that I cared, and I've never worried about my size as I was always small enough to get away with it). Since menopause and leaving work I am now hugely blubbery around the back and belly, and although I still look OK in the right clothes, I have to admit I'm a blob these days. But I still weigh less than 8 stone!
My MIL is in her 90s and struggles with her weight. She is slim in the hips and legs but a bit curvier than she would like around the top half. She has shrunk over the years and is probably 5 ft now. Recently she told me she was 13 stone, and I was gobsmacked. I can't see how she can weigh that much. I can't see how she is 5 stone bigger than I am!
She has size 6 feet where mine are 4s, but she's not huge at all anywhere apart from being quite buxom. It must be about having big bones or wider bone structure or something. I really think weight is a massively personal thing, and people should only use it to monitor their own ups and downs, rather than comparing to other people, or so-called 'norms'.
We can all tell by looking at ourselves in a mirror, or by trying on our favourite clothes, whether we have lost or gained weight, and whether we are happy with our size. We don't need scales to tell us what is good.
OP - please ignore the scales and just go with your own common sense. You look great to me. If you'd like to be smaller then you can work towards that, if you're happy as you are then that's fine too. If you want to lose weight then knowing your current weight is a good starting point to monitor how any weight loss is going - but it doesn't matter if you are starting from 10 stone or 20. I really think it is a meaningless number except for enabling a person to monitor themselves.
(And yes, I know about BMI but I think that's dodgy too. Mine is low but I know I'm fat, and in the wrong places. I also know that very muscly people such as rugby players always 'fail' the numbers. there are many factors at play...)
