Key Takeaways

  • The number of cobblestones depends on their size.
  • For regular 5”x5” cobblestones, there are about 3-4 per square foot.
  • Smaller 2”-3” cobblestones have 9-10 per square foot.
  • Bigger antique cobbles can have up to 100 per square foot.
  • 1 ton of small cobblestones covers 60 square feet.
  • 1 ton of medium cobblestones covers 40 square feet.

Introduction

Cobblestones are small stones used to pave roads, streets, and pathways. They create a bumpy, rustic look. Cobblestone paths are popular for driveways, patios, and garden walkways. But how many cobblestones make up a square foot?

This article will fully explain the number of cobblestones per square foot. It will cover the factors that affect cobblestone coverage. You’ll learn estimates based on cobblestone size. Research from suppliers provides exact calculations. Read on to discover all about cobblestone square footage!

Knowing cobblestone coverage helps plan projects. With the right number, you can buy enough cobblestones without waste. The information here ensures you get the perfect paved surface. Let’s dive in to learn all about cobblestone square footage!

What Determines Cobblestone Coverage?

Cobblestone coverage depends on the variables below:

Cobblestone Size

This is the most important factor. Smaller stones fit more per square foot than larger ones. Standard modern cobblestones are 2”-6”. Antique cobbles can be 6”-12”. Size dramatically impacts squares filled.

Stone Shape

Cobblestones come in various shapes – square, rectangular, circular. Square/rectangular stones fit compactly with little space in between. Circular cobbles leave gaps, affecting coverage.

Stone Thickness

Thinner cobblestones can pack tighter than thick ones. Their flat profile leaves less open space per square foot.

Layer Depth

Deeper layers need more cobblestones. Two layers double the amount vs. one.

Placement Pattern

A tidy pattern needs cobblestones precisely fit together. Random placement leaves more empty space.

Now that we know what affects cobblestone coverage, let’s see specific estimates!

How Many 5” Cobblestones in a Square Foot?

Five inch cobblestones are a popular standard size. How many of these medium stones make up a square foot?

As a general rule, 3.5-4 standard 5” cobblestones cover one square foot. Here are some exact supplier numbers:

  • Gagne & Son estimates 3.2 5”x5”x9” cobblestones per square foot.
  • Pieces of History calculates 3.5-4 per square foot, depending on placement.

So you can expect around 3-4 average for 5” square cobblestones per 12”x12” square foot.

This accounts for a single layer of compactly placed cobbles. More layers or looser spacing increases the amount needed.

How Many Small Cobblestones in 1 Square Foot?

What about little 2”-3” pebble-sized cobblestones? How many of these small stones make up a square foot?

Here are some estimates:

  • BCA Antique Materials says 100 small cobbles cover 1 square meter (about 9 per square foot).
  • Sand Four Sale calculates 1 ton of 2”-3” cobblestones covers 60 square feet double layer. That’s about 9-10 per square foot.

So roughly 9-10 tiny cobblestones 2”-3” in size lay in 1 square foot space. Again, this is for a snug single layer. Smaller stones pack tighter than larger ones.

How Many Antique Cobblestones in 1 Square Foot?

Antique cobblestones vary greatly in shape and size. These reclaimed stones range from 6”-12” in diameter. Their irregularity makes square footage estimates difficult.

But we can extrapolate based on supplier data:

  • BCA Antique Materials says 100 big antique cobbles cover 1 square meter. That would be around 100 per square foot.
  • Pieces of History notes antique cobblestone coverage depends on stone surface used.

So antique cobblestone quantities per square foot range wildly. You may need as many as 100 per square foot depending on variability.

How Many Cobblestones Per Ton?

Cobblestones are often sold by the ton. How many stones make up a ton? It depends on cobblestone size:

  • For small 2”-3” cobblestones, 1 ton covers 60 square feet double layer deep. That’s 720-960 stones.
  • For medium 3”-6” cobblestones, 1 ton covers 40 square feet double layer. That’s 480-640 stones.

So one ton equates to 480-960 cobblestones depending on size. This calculates based on coverage area and depth.

Tim Wallace Landscape Supply estimates 30 square feet of coverage per ton of cobblestones. That would be 360-480 stones per ton.

How Many Cobblestones for a Path or Walkway?

To find how many cobblestones you need for a path, follow these steps:

  1. Measure the length and width of the path in feet.
  2. Multiply length x width to get the total square footage.
  3. Decide on cobblestone size – standard 5”, small 2”-3”, or antique 6”-12”.
  4. Use the above estimates to calculate stones needed per square foot.
  5. Multiply total square footage by cobblestones per square foot.

For example, a 10 foot long by 3 foot wide path is 30 square feet total. With 4 medium 5” cobblestones per square foot, you would need 30 x 4 = 120 cobblestones.

Make sure you buy extra in case of breakage or need for deeper layers. It’s better to have too many than not enough!

How Many Cobblestones for a Driveway?

Follow a similar process to find how many cobblestones you need to pave a driveway:

  1. Determine the driveway’s length and width in feet.
  2. Multiply length by width to calculate total square footage.
  3. Choose a cobblestone size – antique, standard, or small.
  4. Use square footage estimates to find number needed per square foot.
  5. Multiply total square footage by cobblestones per square foot.

For example, a 10 foot wide by 50 foot long driveway is 500 square feet total. With 4 medium 5” cobblestones per square foot, you would need 500 x 4 = 2,000 cobblestones.

Order extra 5-10% more due to shape variances, breakage, and multi-layer depth. Precisely calculating cobblestone driveway coverage takes site measurements.

How Many Cobblestones for a Patio or Courtyard?

Patios and courtyards also need cobblestone calculations. Follow these steps:

  1. Measure patio length, width, and any irregular shapes.
  2. Calculate total square footage.
  3. Pick appropriate cobblestone size.
  4. Multiply total square footage by cobblestones per square foot.

For example, a 10 x 10 foot square patio is 100 square feet. With 3.5 small 2” cobblestones per square foot, you would need 100 x 3.5 = 350 cobblestones.

Add extra for multi-layer depth, fill-in gaps, and replacements. Measure precisely including curves, angles, and patterns. This ensures you purchase sufficient cobblestone quantities.

Key Takeaways

  • The number of cobblestones depends on their size.
  • For regular 5”x5” cobblestones, there are about 3-4 per square foot.
  • Smaller 2”-3” cobblestones have 9-10 per square foot.
  • Bigger antique cobbles can have up to 100 per square foot.
  • Calculate total square footage, then multiply by cobblestones per square foot.
  • Order 5-10% extra for multi-layers, waste, and breakage.

Conclusion

The amount of cobblestones per square foot varies based on stone size and other factors. But you can estimate 3-4 medium 5” cobblestones, 9-10 small 2”-3” cobbles, or up to 100 irregular antique stones.

Measure project areas precisely in total square feet. Then use supplier data to calculate quantities needed based on your cobblestone size. Order a bit extra to be safe.

Knowing the number of cobblestones per square foot helps purchase the right amount. With these simple calculations, you can perfectly pave pathways, patios, driveways and more with minimal waste. Your cobblestone project will have a beautiful, natural stone look
