Frames sizes come in 3 prime units of measurement, namely imperial (feet and inches) metric (centimetres) & the International Standards Organisation (ISO) system . The ISO system is sometimes mistaken as a metric system; in fact it is not, nor is it Imperial, but is an established index of size standards.

In the United Kingdom (UK) a commonly encountered size is A3. This is double A4 and is easily printed with the ready availability of larger printers

The dimensions of A3 are 16.5 inches x 11.7 inches in imperial measurement, or 420mm by 297mm in metric. The key characteristic of an ISO size is it retains its shape (aspect ratio) when folded or doubled.

An A3 frame means that this size picture can be framed by dropping the sheet into the insert area without cutting. Frame sizes by convention refer to the area of picture to be framed, which means (with the exception of borderless clip frames) that the actual frame will be larger than the specified size. The overall visible frame size can be estimated by adding the frame moulding size less a 1/4" to the frame (insert) size.

Size A3 is a popular size for larger certificate and image use, easily scaled, and gives a near 3 by 2 Aspect ratio for photograph use.   Due to its larger size, and hence glass area, this is more prone to breakage than smaller frames, but in transit this is minimised by well established packing solutions utilised by Frames Online UK.  The risk can be circumvented by using styrene safety glass.
