Goliath was either 6 cubits and a span (a little less than 3 meters or 9'6) or 4 cubits and a span (2.1 meters or 6'9). When calculating weight (for muscular or stocky people) you take their height in feet and cube it, which would put Goliath's weight at around either 860 lbs (taller height) or 310 lbs (shorter height).
And there came out from the camp of the Philistines a champion named Goliath of Gath, whose height was six cubits and a span. [1Sam. 17:4] Converted into more modern measurements, this is 3.2 metres (9 feet, 6 inches), if measured by the 18 inch cubit, or 3.5 metres (just over 11 feet), if the 21 inch cubit is used.
