Does LED display size matter?

I'm not looking to build anything anytime soon, but I'm doing research to build my own stereo system. I'd like to add a music decoder with a built in LED display, however the display is smaller than what I'm thinking about using. Does it matter if I replace the small one with a larger one, or would I need to do something more? Sorry if this is a noob question, I'm just starting out with more advanced electronics than I've done before.

Hello,

What type (number) of dispay is used?
What type of display do you want to use?
There may be voltage and current differences.

Its a 4 digit 7 segment display with smaller led icons. From what I can see from the pictures, there are only 7 pins. I'd like to use a 14 segment display, along with smaller led icons as well.

Hello,

14 segment leds displays will need an other kind of driving.
What circuit will be driving the 7 segment leds?
How do you want to convert that to the 14 segment leds?
versus

What led icons will also be displayed?

I have no idea right now. I'm going to need to learn a lot more about circuits before I even consider attempting to mess with them. Thank you for letting me know I need a bit more experience before diving into this lol
