Screen resolution is important for those who make 2D games – they often need to figure out which minimum resolution they should support. Here’s some statistical information which might help out making decisions regarding screen resolutions (this might come handy also when you design a website…). It looks like 1024×768 screen resolution as the minimum is a good choice – and there’s no point considering 640×480.
Out of almost 90 000 visits roughly 97% percent of visitors had bigger screen resolution than 800×600. Only 2.77% had 800×600 and only 0.04% visits were made using 640×480 resolution (that’s 40 visits out of 90 000 using 640×480 – which sounds very small to me). There were some tens of visits made using bit more strange resolutions like 480×272 or 240×160, but the great majority supported bigger screens.
Here’s an image about the situation.
While it’s true that there are some considerations (like the fact that I’ve designed the site for screens wider than 800 and that those people who have smaller screens might visit more often if the website was designed to suit their screens better) I must point out that the stats looked quite similar when my site design was made for 800×600 screens. The small number of those resolutions made me decide to use wider layout.
Anyway, this is only one piece of stat, and I recommend checking out some other statistics (from year 2006 – not any older) from other sources if you have trouble making the decision. But – to me – it looks like 1024×768 as a minimum should cater for most people. If you are planning your 2D game, it looks like there’s no need to plan for 640×480 resolutions. 1024×768 should be fine, and 800×600 as a minimum is definitely okay.
