What are the common weights for sandwich sizes?

The correct answer highlights the common weights for sandwich sizes that are typically offered in a range that accommodates both lighter and heartier options. Sandwiches are often crafted with standard weights to ensure that customers receive a consistent portion, whether they are looking for a lighter meal or something more filling.

The weights of 2.5 ounces, 4 ounces, and 6 ounces are representative of smaller size variations that cater to different appetites and allow for flexibility in menu options. This range is common in many delis and sandwich shops, where smaller sandwiches may be used for lighter meals or as part of a combo, while larger sizes satisfy those looking for a more substantial bite.

In contrast to this, other options provided either offer weights that are not typically used or create sizes that may not align with typical consumer expectations for sandwich servings. This makes the selection of 2.5, 4, and 6 ounces more relevant and practical in the context of common sandwich offerings.
