Coarse builder’s sand for structural base work under pavers and slabs.
10 Tips for Sand Coverage: A Beginner’s Guide
Tip 1: Sand Isn’t One Product, It’s Several Different Ones
Builder’s sand, play sand, masonry sand, and polymeric sand each serve a different structural or functional purpose, and they aren’t interchangeable. Picking the right type for your specific project matters more than picking the right amount.
Tip 2: Match Sand Type to the Job, Not the Bag That’s Cheapest
Builder’s sand is the standard for base layers under pavers or decks. Masonry sand suits pointing and mortar work. Play sand is graded soft and clean for sandboxes, not structural use. Using whichever bag is cheapest instead of the right type is how projects end up needing to be redone.
Tip 3: Depth Tells You What Layer You’re Actually Building
One inch suits a leveling layer, two inches suits a paver base, three to four inches covers general fill needs, and six inches is standard for a sandbox. Choosing depth based on your specific layer, not a guess at “enough,” keeps your material total accurate.
Tip 4: Polymeric Sand Is Worth the Extra Cost for Paver Joints Specifically
Polymeric sand hardens when it gets wet, locking pavers in place and resisting weeds and insects working up through the joints. Regular sand in the same joints stays loose and washes out with rain and repeated foot traffic, so it isn’t a true substitute for joint work even though it looks similar in the bag.
Tip 5: Measure Your Area, Then Match Depth to the Layer You’re Building
Enter length and width for your project area, then choose the depth option that matches the specific layer, leveling, paver base, or sandbox, rather than defaulting to a middle number. Different layers on the same project need separate calculations.
Tip 6: Bedding Sand Under Pavers Should Stay Thin
About 1 inch is standard, and going past 1.5 inches works against you rather than for you. A bedding layer that’s too thick lets pavers shift and settle unevenly instead of sitting stable on a firm, thin base.
Tip 7: Sand Is Sold by Weight, So Know Your Tonnage
One cubic yard of sand weighs roughly 1.3 to 1.5 tons, so multiplying your cubic yardage by about 1.4 gets you the tonnage figure the calculator provides, and what you’ll actually order from a supplier.
Tip 8: Don’t Substitute Play Sand for Structural Work to Save Money
Play sand isn’t compacted or graded the way builder’s or masonry sand is, so using it under pavers or as a base layer leads to poor drainage and uneven settling. It’s the right choice for a sandbox and the wrong choice for almost everything else on this calculator.
Tip 9: Avoid the Mistakes That Lead to Redoing the Layer
Common errors include using the wrong sand type for the job, building a bedding layer thicker than 1.5 inches, using regular sand where polymeric sand was needed for paver joints, and skipping compaction of the sub-base before spreading sand on top. Any one of these shows up later as shifting or drainage problems.
Tip 10: The Right Type and Thin, Correct Depth Is What Makes Sand Work Hold Up
Choosing the correct sand type and keeping bedding layers thin and properly compacted is what keeps pavers and hardscaping locked in place and draining well for years. Getting this layer right is easy to overlook since it’s invisible once the project is finished, but it’s what everything else sits on.

Frequently Asked Questions About Measuring for Sand
How much sand do I need?
To find how much sand you need, multiply the area’s length and width in feet by the depth in feet (divide inches by 12) to get cubic feet, then divide by 27 for cubic yards. Sand is often sold by the ton, and one cubic yard of sand weighs roughly 1.3 to 1.5 tons, so multiply cubic yards by about 1.4 to estimate tonnage. For example, a 100 square foot area at 2 inches deep is about 0.6 cubic yards. Our Sand Calculator returns cubic yards and tons.
What type of sand should I use for my project?
Different projects call for different sand. Use bedding or ‘paver’ sand under and between pavers; masonry sand for mortar and brick-laying; play sand (washed and screened) for sandboxes; coarse ‘sharp’ or concrete sand mixed into concrete; and fill sand for backfilling and leveling large areas. Polymeric sand is a special joint sand that hardens when wet to lock pavers in place. Match the sand type to the job, since the wrong sand can compromise drainage or strength.
What’s the difference between polymeric sand and regular sand?
Polymeric sand contains additives that, once swept into paver joints and activated with water, harden into a firm binder that locks pavers together, resists weeds and insects, and stays in place during rain and washing. Regular joint or bedding sand is loose, can wash out over time, and allows more weed growth between pavers. Polymeric costs more and requires careful installation (the surface must be dry and the excess fully cleaned off), but it produces a longer-lasting, lower-maintenance paver surface.
How deep should the sand layer be under pavers?
Under pavers, spread a bedding sand layer about 1 inch thick (no more than 1.5 inches) over a compacted gravel base—too thick a sand layer lets pavers shift and settle unevenly. This 1 inch leveling course sits on top of the base, not in place of it. After laying pavers, sweep polymeric or joint sand into the gaps and compact. Calculate the 1 inch sand layer separately from your base gravel when estimating materials.
How many tons of sand are in a cubic yard?
One cubic yard of sand weighs about 1.3 to 1.5 tons (roughly 2,600 to 3,000 pounds), depending on the type of sand and how wet it is. Wet sand weighs more than dry sand. Since suppliers often sell by the ton while you calculate volume in cubic yards, multiply your cubic yards by about 1.4 to estimate the tons to order. Always confirm the specific weight with your supplier, as fine masonry sand and coarse sand differ slightly.
