Best practice
When comparing sizes, use "approximately the same size as" to indicate a similarity that isn't exact. Provide context to make the comparison meaningful for your audience. For instance, specify the units of measurement or provide a familiar object for reference. Example: "The new drone is approximately the same size as a small backpack."
Common error
Avoid using "approximately the same size as" when the sizes are noticeably different. This phrase implies a close resemblance, and misusing it can mislead your audience. If the sizes are only vaguely similar, use terms like "larger than" or "smaller than" instead.
