Windows Mobile Development - Screen Size Limitations
The impact of different screen form factors on Windows
Mobile Development
Screen Sizes
Different Windows Mobile devices have different resolutions and
screen sizes. Typically the screen color depth varies between 12 bit (4096
colors) and 32 bit color utilizing a 240 x 320 or 480 x 640 (VGA)
resolution; although there are other form factors as seen below. Most modern
Windows Mobile devices have the capability to seamlessly switch between
landscape and portrait mode.

Impact of Screen Size on Development
The limited (and varied) screen form factors
make it difficult to design one set of intuitive mobile
forms. It isn't practical or feasible to create
different forms for different resolutions. The
challenge for Windows Mobile developers is to
build a set of mobile forms that cater for
different screen sizes yet at the same time
remain intuitive and navigable.
Architecting a
"one size fits all" solution requires
the mobile
forms to be dynamically built (on the fly);
however this approach is somewhat dependent on
the CPU performance and available memory of the
target device.
of the device.also calls for better requires
more dependent upon requires considerable
experience and that works for all sizes without
becoming too diluted or too compromised.
