How to find aspect ratio of a width

[Kippykip]

THIS IS HOW
I couldn't find this anywhere and guessed it when I saw the 4:3 ratio thingys

This is how...
Ready for this??

Say we have 640x480
We want to find 480 with just the 640 number
We know it's a 4:3 resolution but what does this mean?

You do:

640 / 4 * 3

That's how...

You divide by the first number which would be

640 / 4 = 160

Then you times it by the 2nd number

160 * 3 = 480

TADA! Lets try this on another ratio
Lets find the 16:9 resolution from 1920

1920 / 16 * 9 = 1080

HOPE THIS HELPS IN YOUR WIDESCREEN RATIO DETECTION AHAW

That's more on verifying than detecting it. Just divide width by height and refer to this chart:

1.33:1 = ( 4:3 )
1.78:1 = ( 16:9 )
1.85:1 = ( 37:20 )
2.20:1 = ( 11:5 )
2.35:1 = ( 47:20 )

Well yeah verifying is what I meant.
I used it in my game to find out what aspect ratio the game resolution is in so it can scale images and change the fov accordingly
