What Size Strings Does My Viola Need? How Do I Measure My Viola To Determine the Type of Strings It Needs?

D'Addario viola strings are sized by instrument body length in inches. To measure your viola to determine the size sting your instrument needs:

Turn the instrument over and measure its body length along its longest axis (not including the neck or scroll). Then, select the appropriate size string based on that measurement here:

12” = Extra-Extra-Short Scale

13”-14” = Extra-Short Scale

14”-15” = Short Scale

15”-16” = Medium Scale

16”-17” = Long Scale

17”+ = Extra Long Scale

If you measure 15.5" for instance, you will need a medium scale D'Addario viola string (for instruments 15" to 16" inches in length).

NOTE: The instrument sizes are recommendations only.
