Frequently asked questions

Is a 13-inch laptop actually 13 inches wide?
No, the 13-inch measurement refers to the diagonal screen size, not the width. A typical 13-inch laptop's screen diagonal is about 330.2mm, but the actual body width is usually around 300-310mm depending on the bezels and model.
I need to order a 13-inch picture frame from an online store that uses millimeters. What size should I order?
You should look for frames with a diagonal measurement of 330.2mm or approximately 330mm. However, check the product listing carefully—most frame sizes are listed by width and height separately rather than diagonal. A 13-inch frame typically has dimensions closer to 280-290mm wide by 210-220mm tall.
