The number marked on some petal bells is a measurement of the bell's diameter; it is not directly related to the sound of the bell.

Most petal bells marked with a size were made in the mid 1800s or later, although a few early 1800s bells also have size markings.

The term "No" is sometimes seen with the size marking. This is an abbreviation for the word "Number".

Other bell designs seldom have size markings.

Although some people only collect bells that are size marked, there is no real difference in the worth, quality or rarity of marked bells compared with unmarked ones.

Measure your bell across the widest part (see photo.) Round your measurement as follows:

ANTIQUE bells 2 1/2" and smaller:

Round UP to the nearest 1/8 inch for bells 2 1/2" and smaller.

ANTIQUE bells over 2 1/2":

Round UP to the nearest 1/4 inch.

All NEW bells:

Round UP to the nearest 1/8 inch.

Do not be surprised if your bells don't follow the "rules" presented here. At least one bell manufacturer I am familiar with did not follow these rules at all.

Also, horse bells makers, like dress makers, were sometimes generous and sometimes stingy in their sizing. One guy's #12 bell might be another's #11.

 

This bell from the mid 1800s is a hefty 2 7/8 inches across
