4 Common Mistakes to Avoid in Measuring the Box (Otherwise Results Will Be Devastating)

We understand that sometimes we miss measuring the small or minor details of the box. That’s where problems arise, and we end up in a situation that can’t be reversed. Even experienced shippers and business owners mess this up sometimes. Here are a few mistakes to avoid:
  • Measuring from the flaps or edges is not a wise solution. Only measure the usable interior space if that’s what matters.
  • Forgetting the correct order is common, so always measure from the top-facing opening and stick to this order: length, width, height.
  • Using external measurements for internal fits, even if the box looks big enough from the outside.
  • Ignoring wall thickness can lead you to problems, especially with rigid or corrugated boxes, as walls take up space. Account for this when sizing something snugly.
