Calculating the area of an irregular lot can prove a challenge for even the
most geometrically-gifted appraiser. WinTOTAL provides a simple utility to
estimate areas using the “average side” method. To use the area
estimator…
- Anywhere in WinTOTAL, place your cursor in the field you’d like to contain
the results of your calculation.
- From the menus, select Tools, Area
Estimator.
- Select the desired units (Feet/inches, meters, miles) from the
Units for sides drop-down menu.
- Select the units for the result (Sq feet, Acres, Sq meters, Sq miles, Sq
kilometers) from the Units for area drop-down menu.
- Enter the first measurement in the available box and press
Enter or click Add Side.

- Continue entering additional sides until all dimensions have been entered.
The Estimated Area is calculated as you add sides and displayed in the
Estimated Area box.
- Click OK to place the calculated area into your form.
- If you make an error in one of the dimensions, click Clear all
sides to start over.
- At any time, you can select different Units for area.
