Questions tagged [size]

For questions seeking answers about the size of an object or creature. Size is measured in terms of height, width, length, volume, circumference, perimeter, etc. A question seeking to know the limit of a size (e.g., "biggest," "smallest," etc.) are required to explain the conditions and circumstances that justify use of the superlative. Questions about weight, percentage of an amount, etc. may not use this tag (see the "ruler rule" in the tag wiki).
