Multi-Depth Boxes — Standard Strength

Cardboard Boxes 4 U offers 80 SKUs of multi-depth boxes ranging from 4" x 4" x 4" up to 36" x 36" x 36" (inside dimensions). Both standard corrugated and heavy-duty variants are available across this size range, covering small parcel to large freight applications.

No special carton sizing tool is required. The pre-scored sides allow you to use a standard utility knife to cut the box down to your desired height. This makes resizing quick, easy, and accessible for any warehouse or fulfillment operation without additional equipment investment.

Standard multi-depth boxes use single-wall corrugated construction suitable for most general shipping and e-commerce applications. Heavy-duty variants feature reinforced corrugated construction for increased stacking strength, making them ideal for heavier products, industrial shipments, or environments where boxes are stacked during storage or transit.

By replacing multiple fixed-height box sizes with a single adjustable carton, multi-depth boxes reduce the number of SKUs you need to purchase and store. This lowers procurement complexity, frees up warehouse space, and minimizes the risk of running out of a specific box size during peak fulfillment periods.

Yes. Multi-depth boxes are widely used in e-commerce fulfillment because they accommodate products of varying heights without requiring a large inventory of fixed-size boxes. They help reduce void fill needs by allowing a closer fit around products, cutting material costs and improving the unboxing experience for customers.

Cardboard Boxes 4 U corrugated boxes comply with ASTM D5118 and ASTM D4727 standards for corrugated and weatherized packaging, as well as CSA Class Code A. Products also meet WRA and MPA standards for water resistance, and corrugated strength ratings such as ECT-44 and ECT-48 support freight carrier compliance.
