Making UI work for ultrawide games & applications

Wide ratio Support

In 2022 the popularity of different aspect ratio monitors are rising, one of the most popular type of monitors for gaming are Ultrawide and Super Ultra-wide spanning an aspect ratio of 21:9 & 32:9.

Imagine this, you buy a new game for 50$, you boot it up, and you set your resolution support, next thing you know your UI is so far apart you need to rotate your head a good amount to be able to see things properly. What do you think is going to happen next? Are they going to change their resolution of their $1000 monitor, or are they going to just quit the game? Most of the time this can go nasty, no one wants to play not in their native aspect ratio.

This is such an easy thing that can be overlooked and alienate an ever-growing section of hardware in the pc industry.

What is true wide support

Many people will say that adding wide support is just making sure anchors for UI are in place properly, but I disagree, just having anchors in the correct place is not enough. As nice as wide monitors are, a lot of the time the extra vision you gain is not actual focus vision you can pay attention too.

This is not good enough, as we can see in this example our weapon bar, and mini map for this super ultrawide ratio 32:9 are way too far apart, this is not really viable for primary visual feedback for the player.

The Problem

Let's take a little look at a curved ultrawide monitor, and take notice to what is in focus vision.

As we can see from the view cone, I have highlighted the average viewing area that is in focus, and the outer areas are still in vision, but it's hard to read important data from the sides.


A good solution for this is enabling padding to shift the UI tighter towards the focus area. This can be a very effective way to handle this, however, it requires that the UI is set up correctly with good resizing support. A good example of this is using as little static UI transform data as possible and enabling a slot system to correctly size things, without this shifting the UI could turn out with overlapping UI-elements or undefined behaviour.

As long as the UI is set up to scale well, then we can create a UI wrapper to handle padding the sides. We are able to give the user the option to compress the UI to have better vision focus for them without having to make the whole UI a modular system, which can be a monolithic task depending on the game.
