See your height after limb lengthening.
Lengthen your thigh, shin or upper arm on your own photo and compare before and after at the same scale, as a photo or in 3D. Free, no account, nothing uploaded.
See the change on your own body.

Photo + height gives approximate visible proportions, not exact bone lengths or a body scan. Perspective, clothing and pose affect accuracy. Photo previews stretch the legs, and the upper arms when you change them; otherwise arms move with the torso. Arms hanging slightly away from the body preview best. Segmentation edges may be imperfect. The 3D body is an average body until you fit it: drag its lines, or fit it to your photo. This is a visual exploration, not a surgical recommendation or an “ideal proportion” score.
How it works
- Add your height and a photoOne upright full-body photo, facing the camera, head and feet visible.
- Check the landmarksHead, hip, knee, ankle and floor are found automatically. Drag a line if one is off.
- Lengthen thigh, shin or upper armSee your new height and proportions side by side on your photo or as a 3D figure.
New · 360° spin
Now see yourself from every side.
Turn your photo, or your taller preview from the simulator, into a view you can drag all the way around. Made with AI in about a minute.

Questions
Is my photo uploaded?
No. The analysis runs in your browser with a model loaded from this site. Your photo is never sent to a server, saved or shared. Close the tab and it is gone.
How much taller can limb lengthening make you?
Hospital for Special Surgery reports about 3 inches (roughly 8 cm) from femur lengthening, and another 2 to 3 inches from a later tibia lengthening, so 5 to 6 inches in total. What is safe for you depends on your anatomy, the method and how your muscles and nerves tolerate lengthening. Only a surgeon who examines you can say. The sliders here deliberately go further, so do not read them as a target.
Thigh or shin: what is the difference?
Thigh (femur) lengthening keeps your knees at the same height and lengthens the upper leg. Shin (tibia) lengthening raises your knees. Try both and watch the femur-to-tibia ratio.
Can I preview upper arm (humerus) lengthening?
Yes. The Upper arm · humerus slider moves the forearm and hand down your photo and in 3D and updates your arm proportions. Humerus lengthening adds no height, only arm length. Read what the studies report about humerus lengthening for typical gains, recovery and risks.
Can I preview shorter legs too?
Yes. Drag the thigh or shin slider to the left to shorten, to the right to lengthen, or do both at once to see how your height and leg proportions change. Real shortening is limited, so read what the studies report about leg shortening surgery first.
How accurate is the simulator?
It estimates visible proportions from one photo, not bone lengths from an X-ray. Clothing, hair, camera angle and pose can shift results by a few centimetres. Use it to get a feel for a change, not to plan surgery.
What photo works best?
Camera at hip height, 3–4 m away, pointed straight at you. Fitted clothes, bare feet, arms slightly away from your body and a plain background.
Is there a non-surgical way to look taller?
Shoe lifts, height insoles and elevator shoes add a few centimetres instantly and come off at night. See shoe lifts vs limb lengthening for an honest comparison.
Is this medical advice?
No. This is a visual tool. It does not judge whether surgery is right for you or which proportions are “ideal”. Talk to a qualified orthopaedic surgeon before deciding anything.
