HMI symbol sizes

I am trying to make use of symbols and have different symbols that should end up being the same size, however I am finding that even though I set the size of a rectangle in the symbol when I move the symbol to an hmi page with a rectangle the same size the sizes aren’t the same. Similarly enlarging the symbol does not seem to end up getting it to the same size… how do I lock the size of the symbol / size a symbol?
Symbol size set to 1118x395 (the largest rectangle)

Symbol if I set width to 1118 then the height changes to 391.47 and you can see the rectangles are different sizes.
