The measurement tool professionals rely on — and the ruler everyone should already have.
VisualRuler turns any standard card in your wallet — credit card, transit card, library card — into a precision reference for measuring real-world dimensions directly from a photo. No depth sensors. No LiDAR. No special hardware. Just your iPhone and a card you're already carrying.
HOW IT WORKS
1. Place any standard card next to what you want to measure.
2. Point your camera — VisualRuler detects the card instantly and locks the frame.
3. Drag the card corners to fine-tune. Tap to place measurement lines or rectangles.
4. Read results in millimeters, centimeters, or inches. Instantly.
USED BY PROFESSIONALS. BUILT FOR EVERYONE.
Architects verify on-site dimensions before ordering materials. Interior designers check furniture fit before committing to a purchase. Stylists measure garment details from lookbook photos. E-commerce sellers get accurate package dimensions for shipping labels. Product developers document prototype measurements in the field.
And for everyone else? It's the ruler you never knew you were already carrying.
WHAT YOU CAN MEASURE
Furniture, clothing, electronics, artworks, parcels, hardware parts, plant pots, books, screens — anything that fits in the same plane as your reference card. Draw lines or rectangles. Switch between metric and imperial instantly.
WHY VISUALRULER
• Works on every iPhone and iPad — no LiDAR or depth sensor required
• Instant auto-detection — card found, frame locked, ready to measure in seconds
• Always adjustable — drag card corners to recalibrate without losing your measurements
• Metric and imperial — toggle between mm, cm, and inches with one tap
• Photo library support — measure from any photo you've already taken
• Offline and private — no account, no ads, no data collection
ACCURACY
Typically within 1–3 mm for flat objects photographed straight-on. Powered by the same projective geometry principles used in professional photogrammetry — the math actually works.
PRIVACY
VisualRuler collects no data. No analytics, no crash reporting, no account required. Every photo is processed entirely on your device and never uploaded anywhere.
