iPhone with more screen width an height.

Community,

I have an iPhone six SE. I certainly don’t know how to use A third of all the features, but I would like a bigger phone, one with more screen width an height.

My phone is used for our small family business and as a personal phone for myself.

I’m not sure what other information I could share that would help but I would like suggestions from you for a iPhone is larger.

Thank you! : )
