I’ve recently gotten into DnD, and I wanna do something fun first so I wanted to make a DragonBorn Paladin/Wizard but don’t exactly know how to build one. I know I’d have to have 13 or higher on strength and intelligence but that’s about it. Can anyone help? Any help would be great! 

You need a 13 in STR, INT, and CHA.

I recommend starting with paladin for more armor proficiencies. And after that it pretty much depends on what you want out of it.

You may also want to consider switching wizard for sorcerer so you don't need to focus on so many abilities.

Yeah I'd consider Sorcerer - there's a Draconic Bloodline subclass that would probably be right up your alley.

A Paladin/Wizard needs STR to attack with weapons, CON for HP, INT for wizard spells, and CHA for paladin spells.

This means you need 3 strong stats (13 will not be enough to actually do things well - main stats are generally 16+) plus as much CON as you can get with the leftovers.

Sorcerer would remove the need for INT and be much more manageable while still giving you many of the same RP opportunities (unless you really want to be bookish).

Thank you DxJxC and scatterbraind!
