RefSize: Smart Camera Ruler & Photo Measurement
No ruler? No problem! RefSize is a powerful camera measurement tool that lets you measure any object in the real world using a known reference. Whether it's a coin, a credit card, or a business card, RefSize turns your smartphone into a high-precision digital tape measure.
◆ Why RefSize?
_ Unlike traditional AR rulers that can be unstable, RefSize uses proportional scaling based on physical objects you already know. Just snap a photo, and get accurate dimensions instantly!
◆ Key Features:
_ Measure via Reference: Use familiar items (coins, bills, ID cards) as a scale to measure anything next to them.
_ High-Precision Tools: Use our Magnifying Glass (Zoom), drag-and-drop, and fine-tuning controls to mark edges with pixel-perfect accuracy.
_ Measurement History & Lists: Save your measurements (e.g., "Computer Mouse - 12cm") into a dedicated list for quick reference later.
_ Smart Re-use: Once you measure an object, you can save its size and use it as a new reference for future photos.
_ Universal Units: Easily switch between Metric and Imperial units (mm, cm, m, inches, feet).
_ Custom References: Can't find a coin? Add your own custom reference objects by entering their known width or height.
◆ How it works in 3 Easy Steps:
_ Place & Snap: Put a familiar object (like a 1-cent coin) next to what you want to measure (like a computer mouse) and take a photo.
_ Calibrate: Drag the markers to match the size of the known reference.
_ Measure: Adjust the second set of markers to the target object. Boom! You have the exact dimensions. Press "Save" to add it to your history.
◆ Perfect For:
_ Online Shoppers: Check if a piece of furniture or a gadget will fit your space.
_ DIY & Handymen: Measure hardware, bolts, or craft materials on the go.
_ Collectors: Quickly document the size of stamps, coins, or artifacts.
_ Office & School: A handy tool for quick measurements when you don't have a physical ruler.
