8.6" long x 4.7" wide and 2" deep (23 cm x 12.5 cm). Great for long thin things or for cooking for two. Cook all sorts of goodies in this, but we think it would be a great ‘normal’ serving tray for use away from the kitchen. One could even put smaller pots into it: think milk and sugar, two mustards, lots of tiny seeds or herbs to sprinkle. Endless really.
