About Jissun Lab and Privacy
What this site is
Jissun Lab takes published dimensions and draws them to the same scale, as figures and as boxes you can place in your room in AR. It is a reference for questions such as whether a console fits a shelf or whether a bag meets an airline's limit, answered with sizes instead of spec-sheet numbers alone.
Run by the Jissun Lab editorial team, an independent publisher based in Japan. "Jissun" (実寸) is Japanese for "the real dimensions".
Where the dimensions come from
Dimensions are nominal values taken from official standards and from makers' published specifications. They are not our own measurements. Every page lists its sources and the date we checked them.
Some sizes are trade labels with no free standard, such as mattress, rug and photo print sizes. Those pages say so and name the source they used.
About the AR boxes
The 3D boxes are built to the published dimensions. They are reference models for comparing size and do not reproduce the design, color or details of any product.
