Enter the approximate dimensions of your room and choose the type of arrangement you would like to explore. The calculator considers the actual room proportions and the range of tatami sizes available from JapanGarden.

Standard Japanese provides a traditional-style starting arrangement. Practical layout gives greater priority to making efficient use of the available room.
Smaller mats may be used where they provide a better fit.

Indicative tatami floor plan

The diagram shows the approximate proportions of the room and the suggested arrangement of complete mats. Mats are shown individually so that different sizes and orientations can be seen.

Suggested mat sizes

Important: This visual is an indicative planning aid rather than a final construction drawing. Traditional Japanese tatami arrangements depend on the exact proportions and architectural features of the room, including doors, alcoves, pillars and other details.

Standard and practical layouts

Standard Japanese layout provides a traditional-style starting point for arranging the mats, with attention to the proportions and relationship between the individual mats.

Non-standard / practical layout gives greater priority to making efficient use of the available space and can introduce smaller tatami sizes where appropriate.

The calculator therefore provides a useful starting point for discussion. JapanGarden can advise on the final layout once accurate measurements and the details of the room are available.

Please note: This calculator provides an initial indication only and is not a quotation or final tatami laying plan. Accurate room measurements and the proposed layout should be confirmed before manufacture.
