Make geometry easier to see, calculate and understand.
Area and surface calculations show up in schoolwork, design, construction, land measurement and everyday planning. Our goal is to provide clear tools that pair a result with the relevant formula and, where possible, a visual explanation.
The site currently includes an interactive geometry visualizer. The broader calculator directory below is a roadmap; a tool is marked Active only when its linked PHP file exists on the server.
What you can explore
Two-dimensional shapes, three-dimensional solids, coordinate geometry, unit conversion and practical area estimates.
For learning
Review formulas, dimensions, angles and relationships between shapes.
For projects
Plan room sizes, surface coverage and common material measurements.
For exploration
Visualize curves and coordinates, then grow into more advanced geometry.
Geometry & measurement tool library
Use search or category filters. Green means the linked PHP page exists now; amber means it is planned. The 20 priority topics are highlighted as the recommended build order, not falsely presented as working pages.
.php filenames and will become Active when those files are added to the site.321 tools listed across 11 categories.

Built around clear formulas
A useful calculator should explain what it computes, what each input means and which units the answer uses. Our aim is to include formulas, worked examples and relevant limitations as each tool is implemented.
For practical building, land or material estimates, verify dimensions and local measurement conventions before purchasing materials or making professional decisions.
