Having issues with getting a GUI/textlabels to look right

Not sure if this is the right catogory(please point me in the right direction if it isn’t!), but I’m having an issue with making a welcome GUI. It looks fine in studio, but in the uploaded game looks horrible. Should I use something other than text labels, or is there some sort of fix I’m unaware of?
