Free acreage calculator & lot size planner
Trace your land on a map, enter lot dimensions or start with a known acreage. Get area and perimeter, compare project footprints, then estimate fence, lawn and gravel quantities.
Quick rectangular lot check
Rectangular estimate only. For an irregular property, trace the real boundary on the map. Enter only the area you intend to cover before transferring to sod or gravel.
See what your lot size means.
Acreage gives the area. Shape changes the dimensions, fence length and how a project fits.
How big is ¼ acre?
10,890 sq ft. Compare a 100 × 108.9 ft rectangle with a square and your own reference footprint.
Visual comparisonWhat does ½ acre look like?
21,780 sq ft. Change the width and see why equal areas can require different amounts of fence.
Dimensions + perimeter1.5 acres in square feet
65,340 sq ft. Get the exact conversion, compare rectangular layouts and open the visual calculator.
Direct answer + toolMeasure land, compare space, estimate materials.
The same property measurement can answer several questions without forcing you to start from zero each time.
Measure
Trace a lot on a map or calibrate a survey image. Get area and perimeter.
Plan space
Mark occupied areas and test a project footprint plus your own clearance envelope.
Estimate
Reuse dimensions for fence, sod, driveway gravel and project quantities.
Tell AcreSketch what you are planning.
Pick a project and the site will show the measurements you need and the fastest tool to use next.
Planning a garage?
Measure the lot, mark occupied space, then place the real garage footprint and a clearance envelope before you spend on drawings or quotes.
What are you trying to figure out?
Each tool starts from a homeowner question instead of making you decode engineering-style inputs first.
How big is my property?
Trace the boundary on a map to estimate acres, square feet, square metres, hectares and perimeter.
AcreageIrregular lotsHow much usable land do I have?
Mark the house, driveway, pool and other occupied areas, then see what open space remains.
Usable landWill this project fit?
Place a garage, pool, shed, house or custom rectangle inside your drawn property.
Visual fit checkHow much fence do I need?
Turn perimeter into fence length, posts, panels and an optional cost estimate.
Fence planningHow much gravel do I need?
Estimate cubic yards, tons and ordering quantity for a driveway, path or landscape area.
DrivewayHow much sod should I order?
Calculate lawn area, waste allowance and approximate number of pieces or rolls.
LawnWhat percent of my lot is built on?
Compare building footprint with total lot area and estimate remaining open space.
Lot coverageI have a survey or plat image
Calibrate one known dimension on the document, then trace the boundary to estimate area and perimeter.
Survey imageHow should I use the space?
Build a space budget across house, driveway, lawn, pool and other areas.
Project plannerFrom a lot boundary to an actual project decision
Measure once, then use the same property dimensions to plan structures, fencing, lawn and materials.

Five checks a simple footprint cannot answer.
AcreSketch handles geometry and quantities. These items still need local verification before construction or purchase.
Boundary source
Visible fences and aerial imagery can differ from a recorded survey or parcel record.
Clearance around the project
The structure may fit while access, a walkway, deck, working room or equipment space does not.
Local restrictions
Setbacks, easements, lot coverage and HOA rules can reduce where a project may go.
Utilities & drainage
Buried services, septic areas, drainage routes and grades are not visible in a basic footprint test.
Construction access
Equipment and materials may need a wider route than the finished project itself.
Supplier quantities
Use measured areas to size an order, then confirm supplier-specific coverage, density and waste assumptions.
Questions homeowners actually ask
Short guides connect the question directly to the measurement or calculator that can help.
Planning beyond the lot boundary? Learn how much usable land remains and compare a project footprint with its clearance envelope.
How do I calculate acreage?
Use the right formula for rectangles, triangles and irregular properties.
How big is my backyard?
Measure usable yard area instead of relying on total lot size.
Will a garage fit?
Test the real footprint, orientation and available part of the lot.
Measure property online
Trace an irregular lot and understand the limits of map measurement.
How much fence?
Use perimeter and actual fence runs—not acreage.
Get the answer, then calculate your project.
Start with the question you have and use your own dimensions, depth or supplier data.
How much mulch do I need?
Calculate cubic yards and bags from bed area and depth.
How much does a pallet of sod cover?
Check supplier coverage and whole-pallet ordering examples.
How many yards are in a ton of gravel?
Convert US tons with the actual material density.
How many acres is my square footage?
Use the conversion formula and expanded lot-size chart.
How do I find my property lines?
Find boundary sources before tracing a planning outline.
How do I calculate coverage?
Choose percentage coverage or material quantity and depth.
