A Plant Area Calculator (or Plant Spacing Calculator) helps gardeners and landscapers determine exactly how many plants are needed to fill a garden bed based on specific spacing requirements. It translates the “on center” spacing recommendations found on plant tags into a total purchase quantity. It supports both Square Spacing (standard rows) and Triangular Spacing…
The Map Area Calculator is a powerful geolocation tool that allows you to calculate the area of any place on Earth by drawing on a satellite map. Instead of relying on manual measurements, this tool uses GPS coordinates and geodesic math to determine the surface area of fields, roofs, parks, or cities. It is essentially…
The Four Side Area Calculator determines the area of any quadrilateral. It supports standard shapes (Rectangles, Trapezoids) and, crucially, “Irregular Quadrilaterals” commonly found in land surveying. Unlike simple shapes, an irregular four-sided figure cannot be solved with side lengths alone (it could be “flexed” into different areas). This calculator uses the “Diagonal Method” (splitting the…

Whether you call it a flat, an apartment, or a condo, knowing its precise total area is crucial for valuation, renovation, and rent. The Flat Area Calculator is a comprehensive room-summation tool. Instead of asking for a single number, it builds the total area by adding up individual rooms—Living Room, Bedroom, Kitchen, etc. This…
