How much waste should I add for flagstone?

Use at least 10% for simple layouts and 15-20% for irregular borders or heavy shaping.

Can flagstone be dry set?

Yes. Dry-set flagstone usually sits on compacted base and screenings or sand with stable edging.

Both are common. Thin, palletized stone is often quoted by square foot; bulk irregular stone may be sold by ton.

Tips & notes

Assumptions that most often change the final quantity in the field—so you order with clearer eyes.

Use 10-15% waste for irregular shapes and more for diagonal cuts or tight patterns.

Choose thicker stone for dry-set patios and thinner stone for mortar-set work.

Plan a compacted aggregate base plus bedding sand or screenings.

Mix pallets before setting to blend natural color variation.
