How to Choose the Right 12-13" Box

When selecting your corrugated box, consider these factors:

Inner Dimensions vs Outer Dimensions: Boxes are typically measured by inner dimensions. Add 1/4" to 1/2" clearance around your product for safe packing.

Box Strength (ECT Rating): Our boxes range from 32 ECT (light items up to 65 lbs) to 44 ECT (heavier items). Most e-commerce shipments use 32 ECT boxes.

Single Wall vs Double Wall: Single wall boxes work for most shipments. Choose double wall for fragile items, long-distance shipping, or stacking heavy pallets.

Frequently Asked Questions

What size box do I need for shipping 12" items?

For a 12" product, choose a box with 12.5-13" inner dimensions to allow space for cushioning material. If shipping multiple items, measure the total dimensions and add 1-2" to each side.

Are these boxes recyclable?

Yes! All our corrugated boxes are 100% recyclable and made from recycled content. They're eco-friendly and accepted by all municipal recycling programs.

Do you offer custom printing on 12-13" boxes?

Custom printing is available for bulk orders (typically 500+ units). Contact our team for custom branding, logos, or special printing requirements.

How much weight can a 12" box hold?

Weight capacity depends on the box construction. Our standard 32 ECT single-wall boxes safely hold up to 65 lbs. For heavier items, choose 44 ECT or double-wall construction rated for 80+ lbs.
