I don't think the increase is such a big deal.
Firstly, the width barely increases at all.
The height does increase, but the phone is thinner and lighter so shifting it to move your thumb up should be much easier than the 4s or even 5s.
The more I actually consider my iphone usage, the more I am starting to lean toward the 5.5", which at first I thought was utterly ridiculously large.
I think its best to wait and try the phones at an iphone store.
Also in my country apple offer 2 weeks return 100% refund no questions asked. So if you don't like it, you can just take it back.
