6.25” (15.5cm) wide x 9.0625” (23cm) high x 0.875” (2.3cm) thick. 

The book block (the part you write on) is approximately 5.75” (14.6cm) wide x 8.8125” (22.4cm) high x 0.625” (1.6cm) thick.

All books vary slightly, plus or minus 2 to 3 mm, due to fabric, canvas and other differences in thicknesses and materials used in construction.

My Classic journals & diaries are made with 80lb paper, waxed linen thread, & fabrics that are interesting and different. I use the French Link and Kettle Stitches to sew the pages together before encasing them with fabric covered, acid free, archival quality book board.
