Fever Ranges, 11 and Younger

Temperature varies a little depending on how you measure it. For children up to 11 years old, here are the ranges for high, moderate, and mild according to how you took the temperature.

Oral (by mouth), ear, or rectal temperature

  • High: 104° F (40° C) and higher
  • Moderate: 100.4° F (38° C) to 103.9° F (39.9° C)
  • Mild: 100.3° F (37.9° C) and lower

A forehead (temporal) scanner is usually 0.5° F (0.3° C) to 1° F (0.6° C) lower than an oral temperature.

Armpit (axillary) temperature

  • High: 103° F (39.5° C) and higher
  • Moderate: 99.4° F (37.4° C) to 102.9° F (39.4° C)
  • Mild: 99.3° F (37.3° C) and lower

Note: For children under 5 years old, rectal temperatures are the most accurate.
