For publishersWhich AcreSketch tool should I use?
I only know the address
Start with Acreage Calculator & Lot Size Map, trace the boundary and get acreage plus perimeter.
I know length and width
Use the Lot Size Calculator to calculate square feet and acres directly from dimensions.
Planning estimates vs legal determinations
These tools help with early geometry, area, perimeter and material quantities. They do not establish legal property lines, automatically know local setbacks or easements, or approve a project. Critical dimensions, structural requirements and legal/site constraints should be verified from the appropriate official record, plan, supplier or professional.
