Choosing the right bean bag size is one of the most important decisions you'll make when buying a bean bag chair. Size affects comfort, posture support, room layout, and long-term satisfaction. Whether you're buying for a child, teenager, adult, or shared living space, selecting the correct dimensions ensures your bean bag looks good and feels even better.
If you're still comparing construction quality and materials, read our complete bean bag quality buying guide first. This guide focuses specifically on choosing the right size.
Why Bean Bag Size Matters
A bean bag that’s too small won’t provide proper back support. One that’s too large may overwhelm your space or feel difficult to move. The right size depends on:
- The age and height of the user
- Whether it’s for single or shared use
- Available floor space
- The intended purpose (lounging, gaming, reading, outdoor use)
Adults typically require at least 96cm diameter for proper ergonomic support. Children can use smaller sizes safely when designed appropriately.
Understanding How Bean Bags Are Measured
When reviewing product dimensions, remember that most measurements refer to the flat, unfilled cover. Once filled with EPS beads, the shape changes depending on how much filling is added and how the chair is structured.
If you’re unfamiliar with filling types, our guide to EPS bean bag filling explains how density affects comfort and shape retention.
Measuring Your Space Before Buying
Before choosing your bean bag size, measure your available floor space carefully. Consider:
- Doorways and access points
- Other furniture placement
- Clearance for reclining or lounging
- Storage space when not in use
If you're furnishing a small apartment or media room, compact sizes around 80cm–96cm may be ideal. Larger open living areas can comfortably accommodate oversized or lounger styles.

Choosing Size by Use Case
For Gaming
Gamers often benefit from structured loungers or 96cm+ round designs that provide upright back support. Our guide to bean bag chairs for gaming explains the best options.
For Kids
Children benefit from smaller sizes designed for their height and weight. Safety zippers and durable stitching are essential. Learn more in our bean bag safety guide.
For Outdoor Use
Outdoor bean bags often come in larger sizes to create relaxed entertaining spaces. If furnishing a patio or poolside, browse our outdoor bean bags designed for UV and moisture resistance.
Do Bigger Bean Bags Use More Filling?
Yes. Larger sizes require significantly more filling to maintain structure and comfort. Some oversized bean bags ship separately from their filling for easier delivery.
If you're unsure how much filling is required, our guide on how many bags of beans you need explains the calculations.
Common Size Mistakes to Avoid
- Buying too small for adult use
- Not measuring the available floor space
- Ignoring ceiling height for tall loungers
- Forgetting to consider storage space
