Here's a side by side size comparison from Phone Arena:
http://www.phonearena.com/htmls/compare_results.php?phones[0]=2847&phones[1]=2846&phones[2]=2021&phones[3]=2383&area=1- 4.0 x 2.0 x 0.6 (101 x 51 x 14 mm) - Diamond
- 4.0 x 2.0 x 0.7 (102 x 51 x 18 mm) - Touch Pro
- 4.3 x 2.3 x 0.7 (110 x 59 x 18.5 mm) - Mogul
- 4.0 x 2.3 x 0.5 (101 x 59.6 x 13.9 mm) - Touch
It's interesting that the Diamond and Touch are only .1 mm difference in thickness, but it is noted as .1 inches difference. Must be due to rounding numbers off.
FYI, 0.1 millimeter = 0.00393 inch (according to
