Origami World Records

There are dozens of records for origami in the Guinness Book of World Records including most folds, smallest, biggest, fastest time for folding 100 cranes, and many more. Below, I have listed some of the world record that I am interested with:

Smallest Origami Crane

A square 1 mm by 1 mm was used to fold a crane using a microscope and sewing needle by Assistant Professor Watanabe at Nigata University, Japan.

Largest Origami Mosaic

The largest origami mosaic measures 986.46 m² (10,618.167 ft²) and was created by Junior Chamber International Kobe (Japan) at Kobe International Exhibition Hall in Kobe, Hyogo, Japan on 9 August 2015.

45,357 pieces of origami paper were folded into hydrangea shapes and were used to create the mosaic depicting the famous landscape of Kobe port. About 850 people, mainly families and kids, attended the event to make the origami and create the mosaic.

Origami - largest paper crane

The largest origami paper crane has a wingspan of 81.94 m (268 ft 9 in) and was created by 800 people of the Peace Piece Project (all Japan) at the Hiroshima Shudo University, Hiroshima, Japan, on 29 August 2009.

The claimants first created a piece of paper measuring 100 m x 100 m (328 ft x 328 ft) out of smaller paper pieces. These pieces were attached to one another with tape. The wingspan was measured by a surveyor using triangulation.
