Visual Guide + AI Estimate
Compare body fat by picture using broad visual ranges, then upload 1–4 progress photos for a personal estimate with photo-quality and confidence context.

Use these synthetic photo references as broad comparison anchors before reading setup details. They are not exact diagnoses; they help you decide which range your mirror selfie roughly resembles before lighting, angle, pose, and clothing noise take over.
For shirtless male mirror selfies, start with the waist, lower abdomen, chest, shoulder separation, and how much definition survives under flat light.
Clear ab outline, stronger shoulder and chest separation, and limited lower-abdominal softness.
Some upper-body definition remains visible, while the waist and lower abdomen look softer relaxed.
Less visible muscle separation, more waist and lower-back softness, and a rounder relaxed outline.
Midsection softness dominates the visual signal, and most torso definition is hidden in a relaxed photo.
For female mirror selfies, clothing fit, waist and hip outline, leg shape, posture, and cycle-related water retention can shift the visual read.
Visible muscle shape, a more defined waist outline, and less softness through the limbs and midsection.
Softer muscle outlines while still looking active, with waist and hip signals depending heavily on pose.
Less visible definition, more general softness, and clothing compression that can change the estimate.
More visible fat accumulation, less muscle shape, and a stronger need for consistent clothing and angles.

Estimate my body fat rangeA mirror selfie can support a rough body-fat range when the torso, waist, hips, shoulders, and legs are visible enough. It is still a photo, not a tissue measurement, so read it as a range and compare against consistent future photos.
Use the same mirror, phone height, distance, lighting, clothing, and relaxed pose each time. A plain repeatable photo is more useful than the most flattering angle because it makes the body the main variable.
Phone height, close distance, mirror angle, side lighting, flexing, pump, meals, stress, sleep, and water retention can all change the visual read before body composition has meaningfully changed.
One clear mirror selfie is enough to start. Front, side and back photos add views of the waist, torso depth, back shape, posture and balance; they do not remove lighting distortion or prove greater measurement accuracy.
More than a scale ever will. Every scan produces a structured read of your physique — honest, specific, and comparable over time.
We show you an honest percentage range because that’s what a photo-based body-fat estimator can actually deliver. No made-up precision, no pretending.
Chest to calves — see which visible groups lead and which lag.
Left–right balance and proportion ratios, read against your frame — not someone else's.
Deltas per muscle group show direction at a glance.
And a focus plan built around it — not a generic routine.
A body fat percentage by picture is an estimate: lighting, pose, camera angle, hydration and clothing change the visible waist, torso and muscle definition. An 18–22% result is a model estimate range, not a validated statistical confidence interval or a tissue measurement.
Use bright even light, keep the camera level, stand relaxed, and repeat the same setup next time. Consistency matters more than trying to create a perfect or flattering photo.
Your photo is processed to create the analysis. Review the Privacy Policy for current storage and deletion behavior, and use the result as one fitness checkpoint before deciding what to adjust.
Photo-based body fat estimates are informational fitness guidance. They can help you track trends and improve consistency, but they cannot replace DEXA, clinical assessment, or medical advice.
Your transformation, tracked honestly. Follow your estimated body-fat trend, muscle balance, and what changed by region, always read against your own history, never anyone else's body.
Signed-in progress tracking includes a basic body-fat trend and recent comparison. Pro adds regional trends and full saved-analysis comparisons. Explore the body transformation tracker
Privacy and honesty aren't features we bolted on; they shape how the product works.
One purpose: creating your results. Your photos are shared only with the providers needed to create or store them. Guest scans auto-delete; sign in and you can delete your saved photos and results anytime.
Ranges over false precision. No body-shaming mechanics, ever. Results describe, they don't judge. And nothing about your body is used to pressure you.
Free includes an estimated body-fat range, confidence, summary, visible scores, photo-quality guidance, core detail for every available Muscle Balance result, and a limited focus view. Pro unlocks muscle history, bilateral and training-plan detail, deeper trends, strategy, and comparisons.
Free accounts can scan again after a short wait. Pro removes the wait and unlocks full results, trends, and comparisons.
It is an estimate, not a lab measurement. LeanLens is most useful for a realistic range and for tracking visible trends when your photo setup stays consistent.
No account is required to start the free web scan. Saved account history and full reports depend on your plan; check the app before relying on recurring comparisons.
Yes. One clear photo can start the scan; you can provide up to 4 photos. Front, side and back views show different parts of the waist, torso and muscle balance, but extra angles do not guarantee a more accurate body-fat percentage.
