Frequently asked questions

Is a 10-inch tablet screen actually 254mm across?
No, the 10-inch measurement refers to the diagonal screen size, not the width. A 10-inch tablet's diagonal is approximately 254mm, but the actual width and height vary depending on the screen's aspect ratio. For example, a 10-inch tablet with a 16:10 aspect ratio is roughly 216mm wide and 135mm tall.
I need to order a picture frame for a 10-inch print—what size should I specify in millimeters?
A standard 10-inch print refers to one dimension (usually the longer side), which equals 254mm. However, frame sizes are typically specified as width × height. A common 10x8 inch print would be 254mm × 203mm. Always confirm the exact dimensions with your frame supplier, as print standards can vary.
