Calipers work well for this. "Imperial" oval blades measure 29mm x 16mm at the crown, while "Continental" oval blades measure 28mm x 20mm at the crown.
Imperial oval blades were most often found on British bikes and may help narrow down the origin of your frame. N.B. Reynolds supplied blades in either profile, but most other tubing manufacturers only supplied "Continental" profile.
