Size of the SMB Market

A few weeks ago a reader from the U.K. emailed me wanting to know the number of small, midsize and large businesses in the U.S. and U.K. markets.

I knew I had some information but couldn’t quickly find it (isn’t that always the way!).


Today I ran into that information, in a nice pyramid chart. The research firm IDC segments the small business market in the United States for IT-related products and services, like this:

SMB market size

There are several other ways to slice and dice the small and midsize business (SMB) market. You can segment it by revenues, by revenues within industry categories, or even according to buying behaviors.

Segmenting it according to the number of employees, as IDC has done in the chart above, doesn’t work for all purposes. But it’s a good place to start.
