A regular sized 3×3×3 cube has an edge length of about 56-58mm. There is a size range of about 45-60mm, where a cube is comfortable to handle. However, it is great fun to collect different sized cubes, as long a they are of good quality. There are a few manufacturers who produce really crappy cubes. In most cases, these can be identified by faint and/or odd sticker colors, and sharp outer edges.

The
The ** largest** mass-produced cube has a total edge length of about 30cm,
the second biggest one has an edge length of about 18cm.

Leaving out these extremes, most cubes have an edge length from 30mm to 90mm. For more information on 3×3×3 cube sizes, see the Size Categories below.

The first higher order cubes were relatively large and heavy. Sometimes you'd either like a cube that does not take that much space in your luggage, or you'd just want to deal with less weight and size. However, smaller inner layers make turning single inner layers impossible, and require a two-step "forth and back" turning along each of the faces of the layer.

For strange reasons, there are no significantly smaller 4×4×4 cubes on the market.

*Note: After the GAN 328 (28mm) cubes became available, I adjusted the range for "tiny" to less than 25mm.
That keeps this category exclusive.
Whenever new cubes between 21mm and 28mm become available, I might re-adjust the cutover point.*

Here are the Tiny Cubes from my collection. See the photo at the right, cubes left to right.

**CubeLab Mini 3x3 1cm (10.0mm)**

Currently the smallest mass-produced cube. It measures 10.0mm including the stickers. In spite of the size, it still turns OK.**Maru Nanocube (15.6mm)**

Previously available as DIY Kit. The cube itself has about 5mm cubie size, but assembled and including the stickers, it measures 15.6mm. If all casting fins are carefully removed before assembly, the turning quality can become very good.**Vintage Noname 3x3 (20.0mm)**

This cube was available as keychain or necklace version. There is no date given, but I would estimate late 80s or early 90s. All of these are incredibly stiff and need a lot of force to be turned.**YJ Mini Bread 2.0cm Keychain Cube**

This is the smallest pillowed 3x3x3 cube. It measures 20.5mm at the widest point. This one has the best performance in the field, it would qualify as "speed cube" if it wasn't too small for that.**Original World's Smallest Rubik's Cube**

This Rubik's brand cube measures 21.0mm. It is far from turning smoothly, but thanks to the vintage noname, it is not the worst in the field, but still far from good.

This is the list of the largest 3×3×3 cubes as of end of 2022.
