Calculate the base materials and the amount of pavers or patio stones needed for your paving project.
Paver size needs to be entered in inch and fraction format.
If your paver length is 6 3/8", then 6 is entered in the inch field, 3 in the n (numerator) field and 8 is entered in the d (denominator) field.
The gravel needed for the base assumes a compaction factor of -15%. You are purchasing the gravel in loose state and after compaction the volume of gravel will decrease.
Number 6 "part of paver section attached to home or curb" is used to determine which part of your paved area would not need edging support, if you are using this.
