Fill depth
Leave a few inches of the frame showing to keep sand inside. Six inches is enough for toddlers; older kids dig deeper, so 10 to 12 inches is better.
Choosing the sand
Bagged play sand is washed and screened. For big boxes, bulk washed sand can cost less; make sure it is clean and soft, not a coarse concrete sand.

Cover and drainage
A cover keeps out rain, leaves and animals. Put landscape fabric on the bottom so water drains while weeds stay out.
Topping up later
After a season of use, the level usually drops an inch or more. A few bags of the same sand restore it; rake the old sand loose first so the new layer blends in.
Keeping it in place
Plan for some loss each season from splashing, digging and rain. A sturdy border, a fitted cover and fabric underneath keep the sand clean and contained, so you top it up less often.
Measuring the area
Mark the outline on the ground first with paint or a string so measurements match the real shape. Then measure the longest and widest points and the planned depth. Converting to yards and tons is simple arithmetic once those numbers are right.
Common mistakes
Underestimating depth and forgetting extra for settling and spreading are common. So is laying sand straight on sod, which lets grass and weeds come through. Clear and level the ground first.
