Anyone Pro with Twitch emotes and photoshop?

Hey guys!

Was curious if someone of you know how to make pictures/emotes bigger so it will also appear bigger at twitch chat. 

Have done alot of twitch emotes but havent figured out how you can design it that it shows better at chat. Please help.

twitch emote sizes are 28x28 56x56 112x112 + has to be transparent, so im not sure if you need to resize the text within the emote or change the size
