Wong-Baker FACES Calculator

Wong-Baker FACES Calculator for Pain Management. Confirm the person can use the official self-report instrument. A different assessment approach may be needed when self-report is not possible. Discuss pain and function, and reassess after intervention. The number is not a cause of pain, dose instruction or linear percentage of pain.

How this calculator works

The rights-holder history documents the modern even-number values. This page contains no faces, copyrighted labels or administration instructions and does not replace the official self-report assessment. Source: https://wongbakerfaces.org/us/wong-baker-faces-history/

When to use this calculator

Use only when a result has already been obtained with appropriate authorized materials. Do not rate pain by matching the person's visible expression to an imagined face.

Inputs used

  • Final patient-selected 0, 2, 4, 6, 8 or 10 from authorized materials

Clinical interpretation

Confirm the person can use the official self-report instrument. A different assessment approach may be needed when self-report is not possible. Discuss pain and function, and reassess after intervention. The number is not a cause of pain, dose instruction or linear percentage of pain.

Worked example

An official result of 6 is recorded as 6. A typed 5 is rejected for this version, even though 5 is valid on some other pain scales. A later 4 is a lower category, not proof that pain intensity fell by exactly one-third.

Limitations and safety notes

Ability to use self-report and the assessment context matter. Commercial access terms must be checked with the foundation; this page grants no instrument license. The result does not determine analgesic dose.

Frequently asked questions

Can a clinician choose the score by looking at the patient?

No. The official foundation describes this as a patient self-assessment tool, not an observational facial-expression score.
