In plain words

A mid-cap ETF owns companies in the middle of the size range, bigger than the smallest firms and smaller than the giants. Size is share price times number of shares.

ETFIQ counts 305 mid-cap funds, against 897 large-cap and 168 small-cap. Median fees rise as companies get smaller: 0.40% large-cap, 0.50% mid-cap, 0.44% small-cap. Mid-caps sit between the two on swings and trading cost. ETFIQ places each fund by what it owns and shows its benchmark, such as the S&P 500, and gap.
