Size

Maximum length of spleen on abdominal ultrasonography.

A measurement of spleen size is a standard procedure as part of a liver exam, since splenomegaly is a sign of portal hypertension.

Suggested cutoffs are:[1][2]

  • Normal (not splenomegaly): the maximum length is less than 11 cm
  • Moderate splenomegaly: the maximum length is between 11–20 cm
  • Severe splenomegaly: the maximum length is greater than 20 cm

90% confidence intervals of maximum lengths in the normal population have lower limits between 6.4 cm (in short women) and 10.2 cm (in tall men), and upper limits between 12.0 and 14.4 cm (respectively):[3]

Height Spleen length
Women Men
155 - 159 cm 6.4 - 12 cm
160 - 164 cm 7.4 - 12.2 cm 8.9 - 11.3 cm
165 - 169 cm 7.5 - 11.9 cm 8.5 - 12.5 cm
170 - 174 cm 8.3 - 13.0 cm 8.6 - 13.1 cm
175 - 179 cm 8.1 - 12.3 cm 8.6 - 13.4 cm
180 - 184 cm 9.3 - 13.4 cm
185 - 189 cm 9.3 - 13.6 cm
190 - 194 cm 9.7 - 14.3 cm
195 - 199 cm 10.2 - 14.4 cm
Age Cutoff[4]
3 months 6.0 cm
6 months 6.5 cm
12 months 7.0 cm
2 years 8.0 cm
4 years 9.0
6 years 9.5 cm
8 years 10.0 cm
10 years 11.0 cm
12 years 11.5 cm
15 years
  • 12.0 cm
    for girls
  • 13.0 cm
    for boys

For children, the cutoffs for splenomegaly are given in this table, when measuring the greatest length of the spleen between its dome and its tip, in the coronal plane through its hilum while breathing quietly.[4]
