About HomeDims
HomeDims is a reference for the sizes of everyday things around the home: mattresses and beds, kitchen counters, business cards and steel drums. Each page leads with a dimension drawing in inches and centimeters, then answers the practical question: will it fit?
What you will find here
Pages are built like a plan sheet. A labeled drawing at true proportion comes first, then a table of standard sizes, then the clearances people forget, such as walking space around a bed or knee space under a counter. Where sizes vary by maker, we say so and give the range.
Where the numbers come from
Bed sizes follow the long-standing US industry convention and are labeled as common standards. Other sheets name their source on the page: kitchen clearances follow the NKBA Kitchen Planning Guidelines, accessible work-surface height follows the 2010 ADA Standards, card sizes follow national print conventions and ISO ID-1, and drum sizes come from supplier size charts that differ by maker. A typical size is never presented as a legal standard. Metric values use the exact factor 1 inch = 25.4 mm.
What HomeDims is not
- It is not a substitute for the spec sheet of the product you are buying.
- It is not a building-code reference; permits and codes vary by location.
- It does not sell products or take referral payments.
How a sheet is checked
The HomeDims team draws and writes each page. On 12 October 2026 we checked the tables on the home page: all 12 mattress dimensions in centimeters equal the inch value times 2.54 rounded to 0.1, and all 12 room-fit values equal the bed width plus 48 inches and the bed length plus 24 inches. Each drawing uses one scale per sheet, so proportions can be read by eye. A page’s “updated” date changes only when its content does.
Contact and privacy
Corrections and size requests go to the address on the contact page. The privacy policy explains what little is stored, and the terms of use describe how to use the pages.
