I have an array of sizes:
$standardSizes = array("60x60", "90x60", "120x60", "120x90", "120x120", "150x120", "180x120", "240x120");

User is allowed to choose the size of the board they want from these standard sizes, or pick a custom size up to 240x120. The price of a custom board is worked out at the size of the next board up - i.e. if User wants an 80x50 board, they'd be charged for a 90x60.

So, how do I work out what is the next size up? The code I have at the moment is:

if (!isset($_COOKIE['magi']['size'])) echo $warning; else $dims = explode("x", $_COOKIE['magi']['size']);

if (!in_array($_COOKIE['magi']['size'], $standardSizes)) {
	foreach($standardSizes as $size) {
		$size = explode("x", $size);
		if ($dims[0] <= $size[0]) $compWidth = $size[0];
		if ($dims[1] <= $size[1]) $compHeight = $size[1];
	}
} else {
	$compWidth = $dims[0];
	$compHeight = $dims[1];
}
echo $compWidth ." x ". $compHeight;
