I have to disagree with you about the pant legs, if there are no options for different lengths, it’s much better to have them too long. I’m 167cm and even I have a problem of finding long enough jeans, the L30 is always on stock and 32 and 34 are always sold out or not available. It’s so much easier to hem than to add more 😅 We have jean stores here that hem the pants for free for you.
I completely glossed over the tape measure thing so I had to pull out some to check if mine are accurate. It doesn’t look like it in the picture but they are all very very close to each other, the clothing tape measure is the odd one out but that is actually pretty normal, they can stretch over time, especially cheap ones because they are soft plastic.
