When selecting a personal flotation device (PFD), the most critical factors to consider are the wearer's weight and chest size. These measurements are essential for ensuring a proper fit, which directly affects the effectiveness and safety of the flotation device. A PFD that fits snugly will stay in place in the water, providing the necessary buoyancy to keep the wearer safe.

The weight capacity of a PFD indicates how much weight it can support, which is crucial for making sure that the flotation device will properly support the individual. Similarly, chest size is vital to achieving a comfortable and secure fit; a device that is too loose may not provide adequate support, while one that is too tight may restrict movement and cause discomfort.

Other factors such as color, flotation material, design, manufacturer reputation, price, and availability, while important for various reasons, do not directly impact the primary function of a PFD, which is to save lives by keeping the wearer afloat in water. Therefore, focusing on the wearer's physical characteristics will ensure the PFD is effective and functional when it's needed the most.
