What size should every character model be/ can I change it?

Hello everyone, hope you are having a nice day.
How do I make sure that the size of my character stays in scale with everything? Can I tweak the size of the character in unreal engine or do I have to do that in the modeling software?
Thanks for your time.

You can change the scale in the engine. Though it’s better to just build things to the correct scale to start with. 1 unit in UE4 is 1cm so set up your modelling software to use centimetres. It’s best to stick to that, especially if you’re planning to use physics( as this will be based on that scale – not sure if it’s changeable ).

Thanks for the help
