Domande frequenti

Break the shape into rectangles, triangles, circles, or trapezoids you can measure. Calculate each section, then add the areas for the total square footage.
Common options: split into regular shapes and add areas; overlay a grid and count full and partial squares; or use a planimeter or GPS tool outdoors. Splitting into shapes is the most practical for home projects.
Approximate curves with straight segments or use circle and semicircle math. A bay window might be a half-circle plus a rectangle. Curved garden borders can be a string of small trapezoids along the curve.
Yes, and that is usually the best approach. Draw lines to split the space into rectangles, triangles, and other simple shapes. Measure each, calculate with the matching formula here, and sum the results.
Sketch the room first and label measurements. Measure from fixed points like corners. A laser meter saves time. Re-measure anything that looks off. Add 5 to 10% extra for materials.
