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
Look for washed, screened sand sold for play use. Avoid fine silica dust and sharp construction sand. Bulk mason sand is sometimes used for large boxes; ask the supplier whether it is washed.

Keep it clean
Lay fabric under the sand for drainage and weed control, and cover the box when not in use.
Bags vs bulk
A 50 lb bag holds about half a cubic foot, so a single cubic yard is roughly 54 bags. For anything larger than a small box, a bulk delivery or a pickup load from a supplier saves money and trips.
Topping up later
Sand compacts and spreads over time, so expect to add a little each year. Keeping one or two spare bags on hand makes touch-ups easy, and buying the same type keeps the texture consistent.
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.
Common mistakes
Using the wrong sand type is the big one: sharp concrete sand or sand with pebbles is uncomfortable and can damage liners. Another is skipping the ground prep, expecting sand to hide bumps and slopes. It does not; it shifts and washes out.
