Cut pavers should be used to fill gaps along the edge of the pavement that are greater than:

When considering the use of cut pavers to fill gaps along the edge of the pavement, it's important to maintain both the aesthetic appeal and structural integrity of the paved area. Gaps greater than 3/8 inch are significant enough that simply using uncut pavers would not provide a stable or neat finish. By utilizing cut pavers in these situations, landscapers can ensure a tighter fit that prevents shifting and provides a more professional look.

Cut pavers are often recommended for larger gaps because they can be tailored to fit the specific space available, creating a seamless transition that helps with water drainage and supports the overall design. Using cut pavers in gaps larger than 3/8 inch also allows for better support and reduces the likelihood of weed growth or other maintenance issues that can arise from an unfinished edge. Thus, the choice of 3/8 inch as the threshold for using cut pavers is based on practical considerations for installation, longevity, and visual quality.
