Bristol Stool Chart Quiz
Answer 2–3 quick questions and find out which of the 7 Bristol Stool Scale types your stool is — with an explanation of what it means and how to shift toward the healthy range.
How does your stool look overall?
How this quiz works
The Bristol Stool Scale is a widely-used clinical tool for classifying stool consistency. It maps stool into seven distinct types based on shape and texture:
- Types 1–2: Hard, separate lumps — constipation territory.
- Types 3–4: Smooth and well-formed — the healthy range.
- Types 5–7: Soft, mushy, or liquid — loose-to-diarrhea range.
Our quiz narrows down your type with 2–3 simple questions based on appearance (separate pieces vs connected shape), surface (lumpy vs cracked vs smooth), and consistency (solid vs mushy vs liquid). The logic mirrors how clinicians quickly classify stool using the chart.
What your Bristol type tells you
Your Bristol type is a direct readout of colon transit time and water absorption. Hard types (1–2) mean stool sat too long in the colon and too much water was reabsorbed. Liquid types (6–7) mean stool moved too fast for the colon to absorb water at all. Types 3–4 hit the balance.
No single day of stool defines your gut health. The pattern over weeks does. That's why we built PoopCheck: the app automatically classifies Bristol type, color, and consistency from a photo — so tracking is effortless enough to actually do daily, and the pattern becomes visible.
Common questions
What is the Bristol Stool Chart?
The Bristol Stool Chart (or Bristol Stool Scale) is a clinical tool developed in 1997 at the Bristol Royal Infirmary that classifies stool into 7 types, from hard pellets (Type 1) to fully liquid (Type 7). Types 3 and 4 are considered the healthy range.
How accurate is this quiz?
The quiz uses the same classification criteria as clinical Bristol Stool Scale charts. It's accurate for identifying your Bristol type, but not a medical diagnostic tool — it tells you what type your stool is, not what's causing it. For persistent issues, see a clinician.
What's a healthy Bristol type?
Types 3 and 4 are considered the healthy range. Type 4 is often called the "gold standard" — smooth, soft, snake-like, and easy to pass. Occasional drift into other types is normal; it's the pattern over weeks that matters.
What should I do if my type is unhealthy?
For Types 1–2 (constipation), focus on fiber, fluid, and movement. For Types 6–7 (diarrhea), prioritize hydration with electrolytes and avoid dietary triggers. For any concerning pattern lasting more than 2 weeks, or for any blood, mucus, unexplained weight loss, or severe pain, see a clinician.
Is this the same as an AI stool analysis?
No — this quiz relies on your self-description. PoopCheck's AI does the analysis automatically from a photo, classifying Bristol type, color, and consistency in seconds, and tracks the pattern over time. The app is more accurate and much easier than describing stool with words.
