The most commonly used film packet size in dental practices is size 2. This size is versatile and suitable for a wide range of dental imaging needs, including periapical and bitewing radiographs. Size 2 film provides clear images of both anterior and posterior teeth, making it the standard choice for routine dental examinations and procedures.

The use of size 1 is more limited as it is often utilized primarily for pediatric patients or in cases where smaller film is necessary due to the size of the oral cavity. Size 3 film is less commonly used because it is primarily designed for bitewing radiographs but may not adequately capture the detail needed for other types of images. Lastly, size 4 film is reserved for very specific situations, such as for use in occlusal radiographs, and is not routinely used in general practice situations. Thus, size 2 is favored for its applicability across patient demographics and various diagnostic needs.
