Rumor has it that Apple's iPhone 6 will come in two sizes - one with a 4.7 inch display and another with a 5.5 inch display. An alleged leaked document of the schematic of the iPhone 6 provides hints of what we could see in a larger iPhone range.

Spotted by BGR, a diagram posted on a Chinese website and later popped up on French blog — reveals the dimensions of at least one of the models.

The length is listed at 5.9 inches and the width comes in at 3.3 inches, a significant jump in size over the current iPhone 5S. That model is 4.87 x 2.32 inches.

If accurate would have a display measuring about 5.5 inches.
