In my unending research for a new phone, I found this site that makes it super easy to compare phone sizes.
Phone Arena Size Comparison Tool
You can compare the size of all the phones you're interested in. Not exactly the same as holding them in real life but it does give you an idea of what holding each phone would be like. You can also calibrate the page so the sizes match up exactly.
The link above opens up with the Honor 8 already loaded. Pretty slick!

I love Phone Arena for this. I have compared the size of it to the Nexus 5x, and Lumia 950 a few times. Pleased that it is shorter than the 5x, because I hated the tallness of that phone.

That's my go-to when comparing new phones.

That tool is very nice. I use it whenever I want to compare phone sizes

It will be interesting comparing the LG g6 size with other phones on there.
