Stool Form Guide

Bristol Stool Form Scale

Developed at the University of Bristol, U.K., the Bristol stool form scale is a recognized, general measure of stool consistency or form. Using this scale, you can help your physician sort out patterns or changes in bowel habit. Remember, this is intended as a general, not exact, measure. Use this guide to complete your diary and worksheet, and share the information with your physician.

Type 1 Type 1 Stool Separate hard lumps like nuts (difficult to pass)
Type 2 Type 2 Stool Sausage shaped but lumpy
Type 3 Type 3 Stool Like a sausage but with cracks on surface
Type 4 Type 4 Stool Like a sausage or snake, smooth and soft
Type 5 Type 5 Stool Soft blobs with clear-cut edges (passed easily)
Type 6 Type 6 Stool Fluffy pieces with ragged edges, a mushy stool
Type 7 Type 7 Stool Watery, no solid pieces (entirely liquid)
