Our 500 piece large format puzzles have an easy to frame finished size of 27 inches x 20 inches and the same finished size as our 1000 piece puzzles. The puzzle pieces in this puzzle are about twice the size of the puzzle pieces in our 1000 piece puzzles. Due to their larger size they are easier to see and handle. Ravensburger has been making the world's finest puzzles for over 130 years in Germany. Ravensburger puzzles for adults are made to fit precisely - no matter how large or small the puzzle pieces. All of our jigsaw puzzles are precision-made so that every piece fits perfectly, without frustration. Best of all, every single piece in this puzzle is unique, no duplicates, for the perfect interlocking fit. We use extra thick, custom-developed European blue board and hand-crafted puzzle die cutting tools to prevent fraying or peeling puzzle pieces and dust.
