Tatami mats are a key element of traditional Japanese interior design and are known for their versatility, comfort, and aesthetic appeal. If you’re considering adding tatami mats to your home, understanding the correct tatami mat sizes is crucial to ensure they fit your space properly. While tatami mats come in various sizes depending on your needs and preferences, knowing how they measure in feet is essential when planning your room layout.

In this article, we will explore the standard tatami mat sizes in feet, explain how to measure for your space, and provide tips on choosing the right size for your tatami room or furniture setup.

What Are Tatami Mats?

Tatami mats are traditional Japanese floor coverings made from rush grass (igusa) woven over a straw core. They have been used in Japan for centuries as part of home design, particularly in rooms where people sleep or sit, such as the washitsu (traditional Japanese room). Over time, tatami mats have found their way into modern spaces, especially those looking for a minimalist or Japanese-inspired aesthetic.

Tatami mats are versatile, providing both decorative and functional purposes. They can serve as flooring for an entire room, as bedding surfaces when combined with futons, or as standalone pieces of décor. Their thickness and softness make them perfect for creating a peaceful and comfortable environment.

Standard Tatami Mat Sizes in Feet

Tatami mats are traditionally measured in jo (畳), a unit of area specific to Japan. The size of a single tatami mat is based on the size of the tatami mat’s dimensions—typically 3 by 6 feet. However, tatami mats may vary slightly depending on the region or the style of the tatami used. The Japanese standard tatami size can be translated into approximate measurements in feet as follows:

1. Standard Tatami Mat Size

• 3 feet x 6 feet: The standard size for a tatami mat, often referred to as one jo (畳). This size is ideal for use in rooms with traditional Japanese designs, such as tatami rooms or washitsu. A typical tatami mat used in homes across Japan measures around 3 feet in width and 6 feet in length.

2. Larger Mats for Custom Spaces

• 4 feet x 6 feet (1.2m x 1.8m): This size is a slightly larger tatami mat, commonly used for custom or larger rooms, or where more floor space is desired. Some modern homes or apartments may use this size for larger rooms.
• 3 feet x 9 feet (1.8m x 2.7m): For spaces requiring extra long mats or specific use cases, you might encounter mats measuring around 9 feet in length. This size is typically seen in larger rooms or commercial spaces.

How to Measure Tatami Mats for Your Space

When planning to buy tatami mats for your home, it’s essential to measure your space properly. Here are some tips to help you determine the best fit:

1. Measure the Room

Use a measuring tape to measure the length and width of the room or space where you plan to place your tatami mats. Be sure to measure accurately to avoid buying mats that don’t fit.

2. Consider the Number of Mats

If you’re covering an entire room, you may need multiple tatami mats. To calculate the number of mats, divide the total square footage of your room by the square footage of a single tatami mat (approximately 18 square feet for the standard 3 feet x 6 feet mat). Keep in mind that tatami mats are typically laid side by side with no gaps between them.

3. Account for Custom Sizes

Tatami mats come in various sizes, but if you’re looking for something outside the standard 3 feet by 6 feet, many suppliers offer custom-sized tatami mats. For rooms that are non-standard shapes or require a non-traditional tatami setup, measuring and ordering custom sizes can ensure a perfect fit.

Choosing the Right Size Tatami Mat for Your Room

When selecting tatami mats, choosing the right size is key to achieving the look and functionality you desire. Below are some considerations for different spaces:

1. Tatami for Bedrooms (Futon Use)

• Standard Room Size (6-tatami mats): A typical Japanese bedroom uses 6 tatami mats, which can cover an area of approximately 108 square feet. This room typically measures about 9 feet x 12 feet and provides enough space for futons to be spread out for sleeping.
• Small Bedroom Size (4-tatami mats): For a smaller room or studio apartment, you may only need 4 tatami mats (around 6 feet x 8 feet). This size works well for those with limited space but still wanting the comfort and tradition of tatami flooring.

2. Tatami for Living Rooms or Common Areas

• Larger Rooms: For larger living spaces, you may choose to add multiple tatami mats. A 9-tatami mat room (about 12 feet x 18 feet) is often used for family gathering areas or larger open-concept rooms in traditional Japanese homes.
• Custom Room Sizes: If your room or space is irregularly shaped, consider ordering custom-sized tatami mats or opting for a combination of standard and custom-sized mats to achieve a tailored fit.

3. Tatami for Furniture

If you’re using tatami mats for furniture such as tatami platforms, tables, or seating, you’ll need to consider the dimensions of your furniture when selecting the size of mats. For example:

• Tatami Platform: A tatami mat platform is commonly 6 feet x 6 feet or larger, depending on how many mats will be layered.
• Tatami for Seating: Tatami mats can also serve as cushions or seating in a traditional Japanese seating area called a zashiki. In this case, smaller tatami mats (around 2 feet x 2 feet) can be used for floor seating arrangements.

Tips for Maintaining Tatami Mats

Tatami mats require proper maintenance to preserve their durability and appearance. Here are some tips:

• Cleaning: Use a vacuum cleaner with a brush attachment to gently remove dust and dirt. For stains, you can wipe the mats with a damp cloth, but avoid soaking them in water.
• Air Circulation: Tatami mats need to breathe. Avoid covering them with heavy furniture or placing them in damp areas to prevent mold or mildew buildup.
• Rotation: To ensure even wear, rotate your tatami mats every few months to prevent them from becoming uneven or deformed.

Conclusion

Tatami mats bring a traditional and calming aesthetic to any home, and choosing the correct size is crucial for achieving the right look and functionality. While the standard tatami mat size is 3 feet x 6 feet, there are various options available to suit different room sizes and configurations. Whether you’re designing a full tatami room or incorporating them into your bedroom or living area, make sure to measure your space and choose the size that works best for you.

When purchasing, remember to check the mat’s material quality, and don’t hesitate to opt for custom sizes to fit unique spaces. By selecting the right size tatami mat, you can create a serene and stylish environment that reflects the best of traditional Japanese design.
