Flagstone Shapes and Sizes

Most people think flagstone patios are created by fitting randomly shaped stones like the pieces of a puzzle. And while there are, indeed, random designs, many pavers are specific cuts, meant to invoke a specific style or mood.

Flagstone paver designs are available as:

  1. Square cut flagstone. This is a more ordered approach to flagstone patio design.
  2. Random flagstone. This is the style most associated with flagstone patios – fitting the stones together in a pleasing fashion.
  3. Jumbo flagstone. These can be used on many applications: patios, steps, stepping stones, retaining walls, also as a general landscaping feature.
  4. Meshed Flagstone Paver Tile. These are random flagstones that are already laid out for you with a mesh sheet holding them together – similar to glass or mosaic bathroom tiling. While it’s more about the installation,  the mesh can make the job a great deal easier.  It also means the design is set for you.
  5. Custom cut. If you know exactly what you want and can’t find it – it can be cut for you on a custom basis.

Flagstone Types

In practice, there are main types of natural stones that are used as flagstones. Then, you add the variables in design and/or process as above – once aggregated, the types of flagstone and the types of patio design expand into a myriad of choices.

Here are the main natural stones used in flagstone patios:

  1. Sandstone: Sandstone is made from grains of sand and has a rough, slightly textured surface and sand color.
  2. Bluestone: Bluestone is usually sandstone or limestone with a blue/grey tinge.
  3. Travertine: Travertine is a variety of limestone, light in color and highly polished for an almost waxed look.
  4. Slate:  Slate has a dull sheen and comes in every color imaginable.
  5. Limestone: Limestone is white to grey in color and has a grainy texture similar to sandstone.
  6. Granite: Granite is a coarse-grained stone that is highly polished. Colors range from white to pink and gray to back. It’s what many kitchen counters are made from.
  7. Basalt: Basalt is a dark, fine-grained and often shiny rock with few markings.
  8. Quartzite:  Quartzite is a medium-grained very hard stone that is usually white or light-colored.

On top of the actual stone names, you’ll find many flagstones known by their “marketing” names – brand names derived from the location of the quarry or sometimes the quarry name itself.  Pennsylvania Bluestone is one example, this type of natural rock is commonly found in the northeastern USA. Arizona flagstone is another regional type of natural stone commonly used to create patio flagstones.

Flagstones are sometimes called fieldstones and that is totally incorrect. Fieldstones are just what the name says – these are naturally occurring rocks and boulders found above the ground or just under the surface in the fields. They are not flat. Flagstones are flat and need to be quarried and cut into slices.


Random Flagstone Patio Designs

Sometimes, random flagstone patio designs can be the best looking and they are always your own personal design. That’s the plus. They do take a bit longer to lay than some other methods, but it is the most creative of your options. To achieve a design similar to the one shown below and for easier installation, the trick is to use mesh backed pavers.

These stones are made from slate, in random shapes and colors: rust, brown, charcoal and gray – providing for random patterns that are pleasing to the eye. The mulched garden gives a manicured effect to the whole picture. Source

A charming flagstone patio for entertaining

This flagstone patio floor was installed on a mesh, just like tile for a backsplash or a wall (see photo below). While it appears random, you don’t have to make any of the choices, just lay the tile. It’s a great idea to rim your patio with bushes – they will provide a natural break and a natural separation of the areas, as well as a bit of privacy. And we love the hydrangea. If you get tired of blue, you need to know that comes from a PH level of 5.2-5.5. If you’d rather the blossoms come in pink, up the PH in the soil to 6.0-6.2. Voila. It’s magic.

The making of the patio

Follow along, in these three photos (one above, two below) to see the making of a random flagstone patio. It’s probably an easier job if all the stones are the same color or range of color. While adding multiple colors can elevate your look, it does take more time and coordination. And an idea of what you want your completed project to look like!

Add a firepit or water feature

These stones are all in the same color palette – even though there are various shades. The shapes are quite irregular and look quite dramatic together.

Sweeping off your flagstones

A good sweep tidies up the flagstone and shows off the patio’s new design.

Add some in-ground lighting to your flagstone patio designs

While you’re building out your patio, consider adding some in-floor lighting. In-floor (or in-ground) lighting will always give you maximum effect for the money you spend. Lighting can really change the evening look of a space.

Shabby chic flagstone decor

How cute is this patio idea? Just a little corner with a bench and some shabby-chic decor can create a magical ambiance. Who wouldn’t want to sit here with a cup of tea and a good book?

What a view!

Wow. Here’s an incredible flagstone patio idea — build in a firepit. We love the large rocks — and the view’s not bad either. And with the exception of mowing some grass, this patio/garden design does not take a great deal of maintenance.

Firepits are great patio additions

A few shrubs and some colorful flowers add layers to your patio. This is some advanced flagstone patio design, and not one of the easiest to execute, but doesn’t it look great?

You don't have to use cement on your flagstone patio

These heavy flagstones are set among river stones and not cemented in. An attractive technique, but not one for high-traffic zones. It may or may not be sitting on a concrete base. Without one, it does allow for natural drainage of any runoff or rainwater.

Build in some planter boxes made out of flagstones

Building in flagstone planters to your patio design helps break up the color palette with some green and tie the two areas together.

Flagstone Colors

Shop around for the colors you like – there are so many different choices and so many combinations. Literally, hundreds of colors are available including multi-colored stones.

Depending on a state or even a country, different styles of stone and different colors can have different names. And every shop has a different name for the same color – it becomes their brand. So you need to shop around, look at photos, never assume when talking to a seller that they understand the color you are actually referring to. Always have a photo or website link to confirm you mean the same thing.

Flagstone Brand Examples

Most brand names have colors in them. Here are just a few examples.

  • India Silver Grey square cut flagstone
  • New York random Flagstone
  • Arizona Flagstone
  • Idaho Quartzites
  • Pennsylvania Bluestone
  • Muskoka Rock flagstone
  • Armour stone (large size limestones)

Ways of Setting Flagstones When Building Patios

  1. On gravel
  2. On concrete

We’ve discussed this, in concept. If your patio stones are larger and set in gravel, they can provide some stability while doing the environmental thing, and allowing natural run-offs of rain to occur and to feed the ground below. If you do want the grass to grow between your stones for some textural and visual variety, gravel is your only option. Gravel on a cement base will totally impede the growth of any grass. But if it’s a high traffic area, meant for entertaining, concrete may be your better choice as it will give a consistently flat surface.

There is a good installation guide here if you’d like some help getting started.
