Think G19 size, but 0.15" thinner and a single stack (10 round) magazine. This from the Glock website:

Chambered in 9mm Luger the G48 features a compact Slimline frame and a black slide with an nDLC finish. The 10-round magazine capacity makes it ideal for concealed carry.

The frame features elements of the Gen5 and Slimline series such the short trigger distance, a frame with a built-in beavertail, a reversible magazine catch and the incredibly accurate, match-grade GLOCK Marksman Barrel (GMB) and precision-milled front serrations.
