Measure Perimeter is a free online tool for calculating the boundary length around any shape or region in photographs and images. Click to place polygon points around the edges of objects or areas to instantly calculate the total perimeter distance in pixels. Perfect for measuring property boundaries in aerial photos, object outlines in product photography, enclosure lengths in architectural plans, or boundary distances in scientific images. The perimeter measurement tool displays cumulative boundary length you can export with visual edge markers.
Upload your image and click to place points along the edge or boundary you want to measure - the tool automatically connects consecutive points with measurement lines. Click as many points as needed to accurately trace irregular shapes, curved boundaries, or complex perimeters. The perimeter value updates in real-time as you add each point, showing the cumulative distance around your shape. Right-click or press delete to remove the last point if you make a positioning error. Complete your measurement by clicking the starting point again or using the "Close Polygon" button to finalize the boundary. Download your annotated image as PNG, JPG, or WebP with the measured perimeter highlighted and labeled with the calculated pixel length.
Measure property boundary perimeters, lot lines, and parcel edges from aerial photographs and satellite imagery for land surveys and real estate documentation. Calculate fence lengths, hedge boundaries, or property line distances for landscaping projects and perimeter fencing estimates. Measure pool deck perimeters, patio edge lengths, or garden bed boundaries for material estimation in outdoor construction projects. The polygon perimeter tool handles both regular rectangular plots and irregular shaped properties with curves, angles, and complex boundary segments. Accurately trace coastlines, lake edges, or natural boundary features from topographic maps and environmental survey images.
Use the perimeter measurer for construction projects when calculating foundation perimeters, wall lengths, or building footprint boundaries from blueprints and site plans. Landscapers measure mulch bed perimeters, pathway edge lengths, or irrigation zone boundaries for material ordering and job estimation. Scientists measure cell perimeters in microscopy images, lesion boundaries in medical scans, or habitat perimeter distances in ecological research photos. Manufacturers calculate part edge lengths, gasket perimeters, or seal boundary distances from product design images. Urban planners measure park boundaries, block perimeters, or development zone edges from planning maps and zoning documents.
Export measured images at full original resolution with polygon boundary lines and perimeter values automatically scaled for visibility on any image size from small maps to large-format aerial photography. PNG format maintains measurement precision with clear boundary lines and crisp perimeter labels perfect for professional land surveys, property documentation, and technical reports. WebP format reduces file size by 30-50% compared to JPEG while keeping perimeter measurements sharp and boundary lines clear - ideal for uploading annotated property images to real estate platforms or sharing measurement documentation via email. All downloads preserve exact polygon vertex coordinates and calculated perimeter distances for accurate record keeping and legal documentation purposes.
