Custom Size Shipping Boxes
When standard box dimensions do not fit your product, custom size shipping boxes are the answer. Teal Packaging.com manufactures boxes to your exact specifications, so every shipment arrives protected, professional, and perfectly packaged. Whether you are shipping a single SKU or hundreds of products across multiple sizes, we build boxes that fit your items rather than forcing your items to fit the box.
Why Custom Size Matters
Off-the-shelf boxes create real problems for product-based businesses. Oversized boxes waste filler material, increase dimensional weight charges, and make your packaging look cheap. Undersized boxes crush fragile goods and lead to returns. Custom size shipping boxes eliminate both problems by matching the internal dimensions to your product with precision.
- Reduce dimensional weight costs with tighter fits
- Cut down on void fill and packing time
- Improve unboxing experience with snug, intentional packaging
- Reduce damage claims and costly returns
- Present a polished, brand-consistent exterior
Materials Available
Every custom size shipping box is built from materials selected for durability, print quality, and weight. We offer multiple substrate options depending on what you are shipping and how far it needs to travel.
Corrugated Cardboard
Our most popular material for shipping boxes. Available in single-wall (3-ply), double-wall (5-ply), and triple-wall (7-ply) constructions. Single-wall handles most e-commerce shipments. Double-wall and triple-wall are used for heavy items, long-distance shipping, and products that need extra crush resistance.
Kraft Brown
Natural kraft finish gives your boxes an earthy, sustainable look. Works well for brands in food, wellness, home goods, and eco-conscious retail. Kraft corrugated boxes accept flexographic printing and kraft tape sealing cleanly.
White Clay-Coated (CCK)
White-lined corrugated boards give a clean surface for full-color printing. Ideal for retail-ready shipping boxes and subscription boxes where the exterior appearance matters as much as the structural protection.
Recycled Content
All our corrugated materials include post-consumer recycled fiber. For brands with sustainability commitments, we can source boards with higher recycled content percentages and provide documentation for your reporting needs.
Custom Size Range
We manufacture custom shipping boxes across a wide range of dimensions. There is no standard dimension requirement. Submit your exact length, width, and depth and we produce to spec.
- Minimum size: 3 x 3 x 2 inches
- Maximum size: 24 x 18 x 18 inches (larger sizes available on request)
- Wall thickness options: 3mm single-wall, 6mm double-wall, 10mm triple-wall
- Custom die cuts for inserts, dividers, and product cradles
- RSC (Regular Slotted Container), FOL, telescope, and full-overlap styles
If your product requires an unusual shape or a structural feature that standard box styles do not accommodate, our design team will engineer a custom die line for you at no additional charge.
Printing and Finishing Options
Custom size does not mean plain brown. Teal Packaging.com prints directly onto the corrugated substrate using flexographic and digital methods depending on your run size and design complexity.
- 1-color to full-color exterior printing
- Interior printing available for premium unboxing experiences
- Gloss or matte lamination on white-coated board
- Spot UV for logo or label highlights
- Embossing and debossing on outer panels
- Custom sizing printed directly into box design to avoid labeling errors
Who Orders Custom Size Shipping Boxes
Custom shipping boxes are used across nearly every product category. Our customers include:
- E-commerce sellers shipping odd-dimension electronics, tools, or home goods
- Subscription box companies needing consistent monthly packaging
- Food and beverage brands shipping bottles, jars, or perishable kits
- Cosmetics and skincare brands protecting glass components

If your product does not fit a standard box, you belong in this category. Custom sizing is not just for large brands. Our low minimum order quantities policy means you can order a small run to validate your packaging before scaling up.
Free Shipping and Low Custom Production Minimums
Every order includes free shipping. There are low minimum order quantities, so you can order exactly what you need without committing to inventory you do not have space for. Sample orders are welcome before you commit to a full production run.
