Fill up the sandbox with the right sand, and you can watch your kids build a world that’s all their own. The freedom of a sandbox encourages children’s creative development and exercises their fine motor skills, improving hand-eye coordination and muscle control. However, not all sand is appropriate for filling a child’s sandbox. Sand that’s typically used in construction doesn’t go through the same cleaning and processing as sandbox sand, so it’s coarser and can be harmful to kids.

The best sand for sandbox play should be free of potentially dangerous contaminants, like silica dust, to protect your kids while encouraging them to play outdoors. This list of top products includes only silica-free options to help keep your kids safe while they’re playing in the sand.

What to Consider When Choosing the Best Sand for  Sandboxes

Before choosing a product to cushion the ground below the swing set or fill the sandbox, be sure to learn about important features like the type of sand, the texture, and the color. With an understanding of these product factors, it becomes easier to decide which option is the best sand for filling a particular sandbox.


There are three types of sand commonly used for filling sandboxes and sand tables, including natural, processed, and kinetic sand.

  • Natural sand typically comes straight from the beach or the desert. It forms naturally from very small rocks that have eroded. Due to this formation, natural sand is normally coarser than processed or kinetic sand. The manufacturer then washes and filters the sand before packaging.
  • Processed sand is made in gravel pits and quarries. Thorough washing and filtering ensure that it’s clean and safe for kids. However, some products might still contain silica dust, which can be harmful if inhaled in large quantities. It’s advisable to avoid these products and stick to silica-free sand for playtime.
  • Kinetic sand is coated with polydimethylsiloxane, which is a nontoxic, silicone-based organic polymer that goes into soft clay products like Silly Putty. This coating causes the sand to stick together, forming a moldable composition for building in the sand without the need for water. However, kinetic sand typically comes in smaller amounts that are more expensive than either natural or processed sand.


The three types of sand offer different textures.

  • Natural sand has been formed through years of erosion. While this process is effective, sand produced naturally is often coarser than either processed or kinetic sand. However, the texture of this sand makes it easier to clean off when it’s time to go inside.
  • Processed sand is intentionally made, rather than forming naturally through erosion. Manufacturers can choose the appropriate level of processing for sandbox sand, then wash and rinse the product. When the sand is ready to go, it has a fine, smooth texture that can create buildings, roads, and other innovative additions to the sandbox by adding a little water.
  • Kinetic sand goes through a series of processes to remove contaminants, clean and filter the sand, and then coat it with polydimethylsiloxane. This coating gives the sand a smooth, almost soft texture that’s easy to shape, mold, and even cut without adding water. Kinetic sand is a great option for indoor play, and the coating makes it easier to clean up than other types.


Parents often overlook color because they think of sand as having a classic tan appearance, so they look no further. However, depending on the specific product, several color options might be available, including red, green, blue, yellow, purple, and more.

This is a personal preference for most people, so it’s a good idea to check with the kids and see what they prefer. If they can’t decide on one color, some kits come with multiple colors.

White sand looks great in the sandbox, and any bugs, feces, or debris will stand out against a white background, making it easy to keep the sand clean. You always can fill a sandbox with tan or white sand, then add a small play set of colored products for molding and building.

FAQs About Sandbox Sand

For those still unsure of the best type or quantity of sand for a sandbox or sand table, continue reading to explore some common questions.

Q. What is the best type of sand for a sandbox?

The best type of sand for a sandbox has a nontoxic and silica-free mix, ensuring that kids are safe while they play. If the sand is safe, it’s best to choose a product that has the most appealing features for the children, like assorted colors or the moldable, mess-free composition of kinetic sand.

Q. How much sand do I need for my sandbox?

To determine the volume of sand for the sandbox, follow these simple steps:

  1. Measure the length and width of the sandbox. For circular sandboxes, measure the diameter.
  2. Decide how deep you want the sand to go. Typically, half a foot to 1 foot is plenty for most kids.
  3. Use the length, width, and height of the sandbox to calculate the volume (V = L x W x H). Alternatively, find the volume of a circular sandbox by using this formula V = πr2h, where π is equal to 3.14, r is the radius (or half of the diameter), and h refers to the ideal height or depth of the sand.

For example, if a sandbox measures 4 feet by 4 feet and you want half a foot of sand for the kids to play in, then the total volume you would need to fill the sandbox is 8 cubic feet of sand. A circular sandbox with a diameter of 4 feet and an ideal sand depth of half a foot needs about 6.3 cubic feet of product.

Q. How often should I change the sand in a sandbox?

Change the sand in the sandbox once every 1 to 2 years, depending on how frequently kids use the sandbox. It’s a good idea to store at least one bag of sand (plus all the toys and accessories) in a deck box or garage to top off the sandbox when necessary.

Q. How do I maintain sand in a sandbox?

Properly maintain the sand by regularly raking it to remove any debris, and check for bugs or animal feces. Keep the sandbox covered whenever possible, but make sure to allow wet sand to dry properly before covering. Otherwise, the sand can begin to grow mold. Also, it’s advisable to replace the sand about once every 1 to 2 years.
