How much sand in inches for a horse arena?

3-4 inches of sand is enough.  You want to cushion the impact of the hooves to the ground.  If you get too deep, it becomes stressful on bones and ligaments.\n\nAlso, have the base of your arena (packed decomposed granite) graded on a 2% incline, to allow for drainage.

The gravel chips have density about 2.9 to 3.0 gm/cc.  The problem is estimating their packing factor.  Using 0.55, we have say 1.62 gm/cc therefore 1.62 tonne per cubic metre.  The actual chip size doesn't come into the calculation, so sand ought to be the same, except that if the grain size varies a lot then the packing factor could maybe go up to 0.65 as small grains fill the spaces between larger grains, but still just under 2 tonne/m3.

Horse heigh is measured in "hands"\n\nA "Hand" is a unit of measure equal to 4 inches, used to measure the height of a horse at the highest point of the withers. The number of whole hands is properly followed by a period, then the remaining height in inches. Thus a horse who measures 5 feet and two inches at the withers would be designated "15.2 hands". \n\nFrom the following image ( http://en.wikipedia.org/wiki/Image:Horse_parts.jpg ) you can see that the withers are just at the base of the horse's neck.\n\nThe size of horses varies, depending on the breed. The cutoff in height between what is considered a horse and a pony is generally 14.2 hands, though some smaller horse breeds are considered "horses" regardless of height. Light horses such as Arabians, Morgans, Quarter Horses, Paints and Thoroughbreds usually range in height from 14.0 to 17.0 hands and can weigh up to 1300lbs. Heavy or draft horses such as the Clydesdale, Belgian, Percheron, and Shire are usually at least 16.0 hands tall and can weigh up to 2000lbs. Ponies are no taller than 14.2 hands, but can be much smaller, down to the miniature horse, which can be the size of a large dog.

Lot is not a standard size like acre or hectare.\n\nA lot can be 20' by 20' or 10' by 350' or any other number of combinations.

Depends on the flooring in the stable. You may want to look into rubber matting for your floor. It helped my horse. If that isn't an option. More shavings I guess. Good grooming always counts. I don't know how many times I've been to a competition and seen horses who were half heartedly groomed. Nothing done with the hooves. No braids. If your going to go, go all the way.

The average width of a horses behind. No joke. No really...I'm not kidding. Look at the history of Roman road architecture.

Q. What is the Size of a Volleyball Court?\n\nA. Indoor courts are the same size for the FIVB, USAV, CVBA and most sanctioning bodies - 18m x 9m (29'6" x 59'). Indoor courts also have an attack line that runs parallel and 3m (9'10") behind the center court line. Line widths are 5 cm (2") wide. Some beach courts are slightly larger measuring 30 feet by 60 feet. However, in 2001 FIVB and soon after the AVP shortened the doubles beach court to 16m x 8m.

A shire horse (or any other "heavy horse" breed) can weigh up to 2,000lbs.  The average racehorse can weigh up to 1,500lbs, dependent on how tall the horse is.\n\nShire's range in size from 16 to 18 hands (although taller ones have been recorded), and thoroughbreds from as small as 14 hands up to about 17 hands.

Use 12" of sand. Hold it in the area by building a box with 1x12 pressure treated wood. Sink that about 8 - 10" under the ground level so the kids don't have to step up over it so far. I'd put a bumper guard on the top of the 1x12s also so that no one gets hurt by the top of the board either. Don't just go buy any old sand, make sure that you specify what you will be using it for so that you get some clean stuff. \nAll the equipment should be mounted in the dirt UNDER the sand and reinforced with concrete where/when needed. Swingsets and climbing equipment should be secured in this fashion without question.\nHope that helps
