Indeed it is 5000 miles long. It starts from Hushan Great Wall in the east and ends at Jiayuguan Pass in the west, and this distance is much longer than that from California to Florida.

It is 5000 miles long because it is windy and adds up to 500 miles

It is really that long!!!
Infact it is the only building u could see from moon!

Have been researching for a work project and have read sources listing the length as about 3900 miles of actual wall, 200 miles of trenches, and 1400 miles of natural barriers like hills and rivers. Also have read several sources that say No, you can't see it from the MOON, but you can see it from space (as in, orbit around the Earth.)

we all may be right but the only way to know the measurement and how far the great wall streches would take many days of hardwork but i don't see anyone with a yardstick measuring the great wall so we all don't know what the measurment of the great wall of china
