Buoyancy Calculator

Proper weighting is critical for safe and comfortable diving. Too much weight increases air consumption and fatigue, while too little weight can make it difficult to maintain depth or perform safety stops.

This calculator provides an estimate based on your body composition and equipment. Factors that affect buoyancy include:

• Body composition - fat is more buoyant than muscle
• Equipment - tank material, size, and exposure suit thickness
• Water type - saltwater provides more buoyancy than freshwater
• Breathing patterns - lung volume affects buoyancy

As you gain experience, you'll develop a better understanding of your personal buoyancy needs and may require less weight as your skills improve.
