# How do I know the actual size of type in a "web" intent document?

I'm designing in a document set for iPhone 6plus pixel resolution (1334x750) and need to know how the type size translates. For example, when I designate some text to be 30 pt., in the real world when viewed on the iPhone it's something much smaller than that... perhaps 12 pt. This has something to with the number number of pixels in canvas... but how do I convert?

Web intent docs are set to export at 72 ppi which means 1 pt = 1 pixel.

So how do I calculate the real point size of type? I'm not good at math, I need to be told how to do it.

If you're creating for a device then you test it on the device to see how it looks. If it looks too big, make it smaller...too small, make it larger.

There is no rule for this other than, if it looks good it is good.

You mean the regular iPhone6? The 6plus runs at 1920x1080 at 401ppi and the 6 runs at 1334x750 at 336

You could get a visual translation by setting your InDesign Zoom Level so the window's physical diagonal dimension matches the iPhone6's 4.7" diagonal.

The percentage for the iPhone6 1334x750 page would be (72 / 326) * 100, or 22%

For the 6plus it would be (72 / 401) * 100, or 18.0%, but you would have to set up your document to be 1920x1080 pixels

So how do I calculate the real point size of type? I'm not good at math, I need to be told how to do it.

For output and display at 100%, InDesign sets the physical dimension of a pixel as 1/72", so the relationship between type's printed size and the iPhone's displayed size is a simple ratio. For the iPhone6 72/326 gets the reduction in relative size from print to display, and 326/72 would be a multiplier. So to display 12pt type the way it would print, set it at 54.4 pt (12 x 4.53). Or, to display a 1 inch square as 1 inch, scale it by 453%.

For the iPhone6 Plus the multiplier is 401/72 or 5.57
