Mahjong Mat Size Guide: Find the Right Size for Your Table

Choosing a mahjong mat sounds simple until you start comparing the sizes. With options from 80cm to 95cm (31.5"–37.4"), four different dimensions, and three surface materials to choose from, it can be difficult to know which one is right for your setup.

The difference between 31.5" and 33.5" may only be two inches, but on the table, those two inches make a noticeable difference.

Here's everything you need to know before choosing your mahjong mat.

Mahjong Mat Sizes at a Glance

| Size | Imperial | Metric | Best for | |------|----------|--------|---------| | Small | 31.5" × 31.5" | 80cm × 80cm | Compact tables, travel | | Medium | 33.5" × 33.5" | 85cm × 85cm | Standard card tables (34") | | Large | 35.5" × 35.5" | 90cm × 90cm | Larger tables, clubs | | Extra Large | 37.4" × 37.4" | 95cm × 95cm | Full-size tables, maximum space |

Before ordering, measure your table. As a general rule, choosing a mat that is 2"–4" smaller than the table width gives you a neat border around the playing surface while leaving enough room for drinks and accessories.

Choosing Between the Four Sizes

31.5" (80cm) — Small, practical, and easy to take with you. This compact size works particularly well on smaller card tables and is simple to roll up and transport. On a standard 34" card table, it leaves approximately 1.25" of table visible around each side, creating a defined playing area.

33.5" (85cm) — Designed to cover almost the entire surface of a standard 34" card table. With only around a quarter-inch of visible table on each side, it provides the largest possible playing area without extending beyond the table. For many home players, this is the go-to size.

35.5" (90cm) — A good choice when you want additional playing room. It suits larger folding tables and club environments where players need more space. On a standard 34" card table, however, the mat extends approximately 0.75" beyond each side, so check your table measurements before choosing this size.

37.4" (95cm) — The largest option, designed for full-size square tables and games where there is a lot of tile volume. It is also the size that many serious clubs settle on when maximum playing space is the priority.

31.5" or 33.5": Which Should You Choose?

The two sizes can both be used on a standard card table, but they create noticeably different looks.

With a 33.5" mat on a 34" card table, only around 0.25" of the tabletop remains visible on each side. The mat fills almost the entire surface, giving you maximum coverage and playing space with very little visible table around the edges.

With a 31.5" mat on the same table, you get approximately 1.25" of visible table around each side. The result is a more contained playing area with a clear border framing the mat.

There isn't a right or wrong choice — it comes down to the look and feel you prefer. If you're undecided, 31.5" is the safer option, as it sits neatly within any standard card table without the possibility of overhang.

Which Material Should You Pick?

The size isn't the only decision. Silk Mahjong mats are available in three different materials, each offering a slightly different playing experience.

18oz Leatherette · 1mm thick — The standard option. It has a smooth, firm surface that protects the table while providing clean tile grip. The 1mm thickness also means it rolls easily for travel without adding unnecessary bulk.

21oz Textured Leatherette · 1mm thick — A heavier leatherette with a textured finish for a more tactile playing surface. Tiles stay in place more decisively, discards remain controlled, and shuffling feels secure. It keeps the same slim 1mm profile while offering more texture underhand.

30oz Neoprene · 2–3mm thick — The cushioned choice. Its 2–3mm thickness provides padding that helps absorb the impact of tiles, making the game noticeably quieter than on the leatherette options. Tiles also feel more satisfying to place and pick up. The surface can be wiped clean with a damp cloth.

All three materials feature a non-slip base designed to lie flat from the first use.

Frequently Asked Questions

What size mahjong mat fits a standard card table? For almost full coverage on a 34" card table, choose the 33.5" (85cm) mat. If you'd rather have a visible border around the mat, go with 31.5" (80cm).

What size do most mahjong clubs use? For standard card tables, clubs typically choose 33.5". For larger playing setups, 35.5" (90cm) and 37.4" (95cm) provide additional space.

Can I put a square mahjong mat on a round table? Yes. Simply centre the square mat on the table and allow the round edge of the table to remain visible around it. For the best fit, choose a mat that is approximately 2"–4" smaller than the table diameter.

What's the difference between leatherette and neoprene? Leatherette is 1mm thick, slim, and firm, offering good grip while being easy to transport. Neoprene is thicker at 2–3mm and provides a cushioned surface for quieter play. Both have a non-slip base and can be wiped clean easily.

What size is best for Chinese mahjong? Chinese mahjong involves more tile volume, so a 35.5" (90cm) or 37.4" (95cm) mat provides the most comfortable amount of playing space.
