It’s that gift giving time of the year. Whether it’s for your family, friends, or you, electronics are always the “IT” item. This year tablets, ereaders and iPads will continue to be hot. And that means you will need to get a case to keep it safe.

There are many different case choices, like iPad cases that open like a book or tablet cases that are more like an envelope. The cases can be made of leather, neoprene (“wet suit material”) or fabrics lined with foam padding. Some go beyond being a case, and are trendy bags that also have a padded pocket specifically for a tablet, and maybe also a laptop.

The real trick is finding a stylish e-reader case that fits. So, in the event that you are giving or getting an iPad or ereader this holiday, here is the list of measurements of the popular models so you can quickly compare:

iPad 2 – 9.5″x 7.31″ x 0.34″
iPad – 9.56″ × 7.47″ × 0.528″
Barnes & Noble Nook – 7.7″ x 4.9″ x 0.5″
Amazon Kindle 2 – 8″ x 5.3″ x 0.36″
Kindle Fire – 7.5″ x 4.7″ x 0.45″
Motorola Xoom – 9.8″ x 6.6″ x 0.5″
HP TouchPad – 9.45″ x 7.48″ x 0.54″
Samsung Galaxy Tab 10.1 – 10.1″ x 6.9″ x 0.34″
Samsung Galaxy Tab 8.9 – 9.1″ x 6.2″ x 0.34″
Samsung Galaxy Tab 7 – 7.48″ x 4.74″ x 0.47″

Just in case you are wondering what you are looking for with those dimensions, think of how you measure a box. The dimensions to compare to be sure that your case fits are the length, width, and depth, not necessarily the screen size.
