What is the size limit for international parcels?

Is there a size limit for international parcels? Ugh, tell me about it! International shipping sizes are a nightmare sometimes. Seriously, who came up with these rules? Like, if you're sending a standard package, it can't be heavier than 2kg, I think. Two kilograms! That's like, what, a couple of bags of sugar? Not much at all. Then there's the whole dimension thing... Length plus width plus depth – all together it can't go over 90cm. And the longest side? Sixty centimeters max. Sixty! I remember once trying to send a framed picture to my sister in Australia. It was just over the limit, like maybe a centimeter. I had to repack the whole thing, find a different frame. What a hassle. And don't even get me started on tubes! It's something like, the length plus twice the diameter has to be less than 104cm. One hundred and four! It's like they're trying to make it difficult. Honestly, it's enough to make you just give up and send an email instead. But then you miss out on the joy of getting a real, physical package, right? So you wrestle with the tape and the box and the measuring tape...it's a whole thing.
