In Adobe Illustrator Constrain Width and Height proportions doesnt work
I don't know why but 'Constrain Width and Height proportions doesn't work
in 'Transform' or 'Properties' panel
Whenever I constrain and move the number up, it creates a weird number
for example, if the shape is 60,60 and when I write down 70 on the height the width becomes 69.256 something like this
so frustrating!!!!!!!!!

today is 2 july 2026
after the new update, Constrain Width and Height proportions in Adobe Illustrator have a problem again. Whenever I constrain the width value the height will follow, for example, if the shape is W2in X H2in and when i want to change only the width to 3in the height will be 3in also. -

still not fixed. i am getting things that are off more than a 0.25 inch which is crazy. such a frustrating bug when trying to use this program in the printing industry.

Definately a +1 from me.
I try to turn off constrain and then change one dimension but the other changes slightly with it. So annoying!
