Sandwich Platter Estimator

How to calculate sandwich quantities?

When planning for mixed groups, the 1.5x rule is a standard catering industry benchmark. It assumes that on average, guests will consume one and a half portions (usually half-sandwiches or smaller rolls), accounting for varying appetites and ensuring full coverage for the group.

Total Sandwiches = Guests × Consumption Rate

Using the Estimator: an example

Imagine you are organizing a corporate lunch for 20 guests with a 'Standard' appetite level. You have selected a caterer that provides platters containing 15 sandwich portions each.

Step-by-step calculation:

1. Multiply the 20 guests by the 1.5 consumption factor.
2. The total requirement is calculated as 30 individual sandwich portions.
3. Divide the 30 portions by the 15-count platter size.
4. The resulting order is exactly 2 platters.

Frequently Asked Questions

How should I handle dietary mixes?
A safe rule of thumb is to dedicate 20% of your total order to vegetarian, vegan, or gluten-free options. Ensure these are clearly labeled to avoid cross-contamination.

Does bread type affect quantity?
Yes. Dense artisan breads, thick wraps, or ciabatta are more filling than standard sliced bread. If serving heavy options, you might lean toward a 1.2x multiplier instead of 1.5x.

Should I calculate portions as halves or wholes?
Most platter sizes refer to the number of pieces (halves/triangles). Always check with your vendor if '1 platter' means 15 whole sandwiches or 15 cut pieces to adjust your input.
