Splits Calculator — Flexibility Progress Tracker
Measure how close you are to doing full splits and estimate how long it will take to achieve them. Enter your current hip clearance from the floor (how far your hips hover above the ground when you attempt splits) and your weekly flexibility gain to see your progress percentage and a time-to-goal estimate.

How does this calculator work?
Enter your current hip clearance from the floor when attempting splits and your weekly improvement rate. The calculator shows your progress percentage and estimates weeks to full splits using: weeks = clearance ÷ weekly rate. Typical gains with daily stretching are 1–3 cm per week, faster at the start and slower near the end.
Formula
How this is calculated
The key measurement for splits progress is hip clearance — the vertical distance between your hip crease and the floor when you sink as far as you can into a split. A clearance of 0 cm means you've achieved full splits. The calculator expresses your progress as a percentage and estimates how many weeks remain at your current rate of improvement.
The weekly improvement rate depends heavily on training consistency. Most people who stretch daily (10–20 minutes of targeted hip-flexor, hamstring and adductor work) gain 1–3 cm of clearance per week in the early stages; gains slow considerably as you approach the last few centimetres. Enter a conservative rate if you are newer to stretching — it is better to under-promise and be pleasantly surprised.
The estimate assumes a constant weekly improvement rate, which is a simplification: in reality, flexibility gains are fastest in the first weeks and taper off near the end. Use the projection as a motivational guide rather than a precise promise. Front splits and straddle splits are roughly similar in difficulty for most people, though individual anatomy (hip socket shape) places a hard ceiling on straddle flexibility that training cannot overcome.
Frequently asked questions
Warm up thoroughly, then sink into your deepest split position. Have someone measure — or use a book standing on the floor — the vertical gap between your hip crease (where your thigh meets your torso) and the floor. Measure consistently at the same time of day (after a warm-up) for comparable readings week to week.
Most adults without prior flexibility training take 3–12 months of consistent daily stretching to achieve front splits. Straddle (middle) splits often take longer due to the adductor muscle structure. Individual anatomy matters — some people have shallower hip sockets that allow greater ROM. Progress is fastest in the first 6–8 weeks.
Flexibility tends to decline with age, but adults of any age can improve significantly with consistent training. Older beginners may find progress is slower and requires more patience. Regularity (daily stretching, even briefly) beats occasional marathon sessions at any age.
