Adobe XD artboard size for 18:9 ratio

[faris21513]

Hey there.

I tried to search the answer on the internet,

and try n error brought me nowhere.

What is the best size for artboard in Adobe XD for the 18:9 ratio screen size?

My prototype phone got 1080 x 2160 pixels, 18:9 ratio (~403 ppi density).

Thanks.

So it's basically 2:1 aspect ratio? In any case I think it depends on if you want to export production assets from XD or not, and if the assets are bitmap or vector. If you are intending to export bitmap at higher resolution, then you may want to use the phone's actual resolution 1080 × 2160. If not, you can use the viewport size (411 × 822 may be? I don't know)

I'm curious what device is 18:9. The recent super wide Android phones are 18.5:9, iPhone X is 19.5:9.
