x2y 4+

Sure, we all know how to cross-multiply. But if you do lots of resizing calculations every day, you can save yourself hours with this simple application.

x2y is a beautifully simple aspect ratio calculator for the iPad, iPhone, or iPod touch. Built for designers and web developers who need to resize images and videos in code, x2y calculates dimensions and percentages for you automatically. Just choose the original aspect ratio or size, enter one of the new desired dimensions or a percentage, and the missing dimension(s) will be calculated instantly.

• Choose from a list of common aspect ratios for even faster calculations.
• Customize the list of common aspect ratios to include your own.
• Swap the x and y coordinates as needed with a single tap
• Double or triple the dimensions of your outputed images with a single tap. (Great for figuring out those @2x and @3x dimensions quickly.)
• Half or one-third the dimensions of your outputed images with a single long tap.
• Solve for either x or y dimension.
• Solve for a particular percentage.
• Solve for diagonal of both ratios
• Round to the nearest pixel, or show up to three decimal places, for more precise results.
• On iPad, choose left or right handed layouts, for better placement of commonly used interface controls.
• Select from several different color themes, to suit your preference
• Sync your custom aspects, selected theme, and more, between all your iOS devices over iCloud.

x2y conforms to the size of your screen. It is fully compliant with Voice Over for the visually impaired.
