Measure Area is a free online tool for calculating surface area and region size in photographs and images. Click to place polygon points around any shape or region to instantly calculate its area in square pixels. Perfect for measuring room floor space in real estate photos, land plot sizes in aerial imagery, object surface areas in product photography, or region of interest areas in scientific images. The area calculator tool displays precise measurements you can export with visual boundary markers.
Upload your photo and click to place points around the perimeter of the area you want to measure - the tool automatically connects points to form a closed polygon shape. Click as many points as needed to accurately trace irregular shapes, curves, and complex boundaries. The area measurement updates in real-time as you add each point, showing total square pixels enclosed by your polygon. Right-click or press the delete key to remove the last point if you make a mistake. Complete your measurement by clicking the starting point or using the "Close Polygon" button. Download your annotated image as PNG, JPG, or WebP with the measured area highlighted and labeled with the calculated square pixel value.
Measure floor area of rooms, apartments, or houses directly from floor plan images or photographs taken from doorways. Calculate land plot sizes, yard dimensions, garden bed areas, or parking lot space from aerial photos and satellite imagery. Real estate professionals use it to verify property listings, measure outdoor deck areas, calculate siding or flooring material needs, or assess usable square footage from architectural plans. The polygon area tool handles both regular rectangular spaces and irregular shaped rooms with alcoves, angled walls, or curved boundaries.
Use the area measurer for home improvement projects when estimating paint coverage, flooring materials, or wallpaper quantities from room photos. Scientists and researchers calculate cell areas in microscopy images, lesion sizes in medical scans, or habitat zones in ecological survey photos. Graphic designers measure design element proportions and white space ratios in layout mockups. Farmers and landowners calculate field sizes, crop coverage areas, or irrigation zone dimensions from drone photography. Construction managers measure foundation areas, roof sections, or paving requirements directly from site survey images and blueprints.
Export measured images at full original resolution with polygon boundaries and area values automatically scaled for visibility. PNG format maintains measurement precision with transparent overlays perfect for professional reports, property appraisals, and documentation. WebP format reduces file size by 30-50% compared to JPEG while keeping area measurements clear and polygon boundaries sharp - ideal for uploading annotated images to project management systems or sharing measurement documentation via email. All downloads preserve exact polygon coordinates and calculated area values for accurate record keeping and verification purposes.
