what sleeve size do i have?

Question

I bought a dress shirt and when i got home and tried it on, the shirt fit perfectly except the sleeves were too short.

I wear normally a 17 1/2 and the sleeves were 34/35.
the package said:

"if you wear a large shirt, then you will wear..." and it shows the suposedly perfect size for you.
well, mine was actually small than I normally wear..so there is no way that key is right.

I tried on another shirt that I already own and the sleeves weren't as short and they're the exact same sleeve length!
any help would be fine.

It was a puritan shirt at walmart.
thanks.
