Easily Calculate the Area of Irregular Shapes
area of polygon
SketchAndCalc is an area calculator for users wishing to calculate the area of irregular polygon shapes.

Start by simply drawing the shape onto the drawing canvas using either straight lines or curves. Alternatively importing an image such as .png, .jpg .gif or .pdf. will allow users to trace around objects over the image. Area and perimeter results are displayed when completing a closed shape.

What sets SketchAndCalc apart is its ability to allow users to set the scale of the drawing canvas by prompted them to draw a known length. Depending on the image or map, landmarks for known lengths could range from a doorway, wall, distance between lamp posts, a scale ruler (if a photograph was used) or floorplan scale indicator etc.

Once set, begin tracing around the irregular shape until it is completely closed. The area and perimeter results are displayed in all common measurement systems in the bottom right corner.

Setting the drawing scale isn't necessary for tracing shapes over a map, as the map automatically adjusts to the magnification level set by the user. The further a user zooms into the map the more accurate the area calculations will become as the curvature of the earth presents some inherent inaccuracies when tracing objects or landmarks from a great distance.

For those wishing to calculate numerous areas over a single image it is possible to clear the canvas of the drawing only, leaving the imported image (and canvas scale) in place ready for the next area calculation.

The drawing tools of SketchAndCalc allow high levels of accuracy and adjustability of vertices. Changing vertex position, manually entering a specific length, and even adding and deleting vertices are possible once the irregular shape is complete.

SketchAndCalc users vary from homeowners looking to calculate the area of a home floorplan, or landscaping project, to architectural practices, automotive, medical and retail industries. SketchAndCalc can even calculate irregular shaped areas in nanometers for those in the semiconductor industry.

Square area in acre's or hectares are also displayed for those wishing to calculate the irregular area of a building plot, parcel of land or large landscaping project.
