Results of the Gunning’s Fog Index (or FOG) Readability Formula

The FOG readability formula is widely used in the health care industry and throughout the entire business community.

The FOG formula takes into consideration (1) the total number of words, (2) the number of words of three or more syllables, as well as (3) the total number of sentences.

Since FOG readability scoring aims for 90% comprehension, except for the SMOG readabiity formula FOG grade level scores are inclined to be higher than the other formulas included in Readability Calculations and Readability PLUS.

As applied in industry and business, many reading experts feel that no technical material should score higher than grade level 14, no business material higher than grade level 12, and no clerical material higher than grade level 8.

Both Readability Calculations and Readability PLUS display this formula’s scoring results on a screen which may contain other formula results as well.
