What Is the Beighton Score?

The Beighton score is a simple screening technique used by doctors and therapists to assess joint laxity, often called hypermobility or double‑jointedness. A free Beighton score calculator provides an online way to quickly obtain your joint laxity score by recording responses to five physical tests. Many people seek a hypermobility test to understand why their joints seem unusually flexible, and this tool serves as a practical first step. It’s important to note that the Beighton scale is sometimes mistakenly referred to as the “Brighton scale,” but the Brighton scale is a different assessment used for specific connective tissue disorders. The Beighton scale, also called the Beighton test online, focuses on five straightforward movements that together give a numerical indication of joint flexibility.

The Five Movements of the Beighton Test

The Beighton test includes five movements, one of which is performed actively by the patient and four that are done passively (the examiner moves the joint). The four passive movements are assessed on both the left and right sides, so the maximum possible score is 9 points. The following table details each movement and how it is scored:

All points are summed to produce the final Beighton score. The joint laxity score helps identify whether a person’s flexibility falls outside the typical range.

How to Use a Beighton Score Calculator

Using a free Beighton score calculator online is straightforward, but ideally a healthcare professional performs the physical tests. Here is a step‑by‑step guide to the movements:

1. Forward bend (active) – Ask the person to keep their legs straight, bend forward at the hips, and attempt to place both palms flat on the floor. If they succeed, check the box for 1 point.
2. Knee hyperextension – With the person lying or standing, gently push the knee backward while the leg is straight. If the knee extends more than 10 degrees beyond the neutral position, award 1 point for that side.
3. Elbow hyperextension – Also known as the double‑jointed elbow test, this involves carefully straightening the elbow beyond its normal limit. A bend of more than 10 degrees backward earns 1 point per elbow.
4. Thumb to forearm – Pull the thumb gently toward the front of the forearm. If the thumb touches the forearm, score 1 point for that thumb.
5. Little finger bend – Hold the hand flat and attempt to bend the little finger backward at the knuckle. If it exceeds 90 degrees, record 1 point for that little finger.

The calculator automatically tallies the points and displays the total joint laxity score.

Interpreting the Results

A Beighton score of 4 or higher out of 9 is generally considered suggestive of hypermobility. However, no sharp cutoff exists; the score must be interpreted together with other clinical signs, symptoms, and diagnostic tests. A so‑called “negative” result (below 4) does not rule out joint laxity, and some people with a low score still experience symptoms such as pain or instability. The Beighton scale calculator is a useful screening tool, not a replacement for a full medical evaluation.

Limitations of the Beighton Scale

The Beighton test examines only a few joints (knees, elbows, thumbs, little fingers, and the forward bend), so it does not capture overall whole‑body flexibility. It also cannot diagnose specific underlying conditions on its own. Despite a normal score, a person may still have connective tissue abnormalities that cause joint problems. Therefore, the Beighton scale should always be part of a broader clinical workup, including medical history, physical examination, and possibly imaging or laboratory tests.

What Causes Joint Hypermobility?

Joint hypermobility can be a harmless constitutional trait, or it can be a sign of an inherited connective tissue disorder. The most common genetic conditions associated with joint laxity include:

• Marfan syndrome – often marked by tall stature, long limbs, and cardiovascular complications.
• Ehlers‑Danlos syndrome – a group of disorders that affect collagen structure; the Brighton criteria (not the Beighton scale) are used for its evaluation.
• Down syndrome
• Loeys‑Dietz syndrome
• Osteogenesis imperfecta (brittle bone disease)

In many cases, double‑jointedness arises from a defect in the connective tissue, particularly the ligaments that normally limit joint movement. Joint laxity can also develop after an injury. If you suspect you or a family member may have an underlying condition, consulting a physician is essential.

When to Seek Medical Advice

The free Beighton score calculator offers a convenient starting point for assessing joint flexibility, but it cannot replace a professional assessment. If you experience persistent pain, recurrent dislocations, or other worrying symptoms, a doctor can perform a thorough examination, consider your medical history, and recommend further testing if needed.
