Large shipping boxes go by a few common names, depending on shape and use:

• Long corrugated boxes for poles, banners, and other elongated items.
• Tall boxes for upright, narrow items.
• Large moving boxes for packing bulky household goods.
• Wardrobe moving boxes designed to hold clothing during moves.
• Side-loading boxes that open on the long edge for easier packing.

You’ll also see strength ratings like ECT-32 and 200 lb test. Matching the style and strength to your item’s size and weight can help improve protection and make packing easier.

There are a few ways to get better value when buying long boxes:

• Compare singles and multipacks—this category includes single boxes and bundled quantities.
• Pick the right size to reduce excess void fill and materials.
• Use multi-depth boxes with adjustable heights so one box fits multiple tasks.
• Select appropriate strength: ECT-32 single-wall can suit lighter items; use heavier ratings only when needed.
• Check pickup or delivery options to choose what’s most convenient for your timeline.

Right-sizing and choosing suitable strength can help minimize extra supplies while maintaining protection.

You can shop very large and extra-long boxes on Walmart.com in the shipping and moving boxes sections.

• Long sizes are available (examples include 36×14×14 and 48×16×16).
• Specialty options include tall, side-loading, and wardrobe moving boxes.
• Availability may vary by location; product pages show delivery or pickup options.

If you’re moving, browse large moving or wardrobe styles; for posters or long parts, look at long corrugated sizes. Compare dimensions and strength ratings to find the best fit for your items.

Long boxes on this page come in a wide range of dimensions:

• Compact: 12×3×3, 12×6×4, 14×4×4
• Mid-range: 18×9×9, 20×8×8, 28×10×10, 36×12×12
• Oversized: 36×14×14, 48×10×10, 48×16×16, 8×8×48

To choose:

• Measure length, width, and height and allow space for padding.
• Match orientation (tall vs. side-loading) to how you’ll pack the item.
• Check strength ratings like ECT-32 or 200 lb test based on the item’s weight.

This approach can help you find a size that fits without excessive fillers.

For long items, a snug fit plus cushioning can work well:

1. Choose a long box close to the item’s length, leaving 2–3 inches for padding.
2. Wrap the item with bubble roll or foam and protect corners/ends.
3. Fill voids with kraft paper or inserts so the item doesn’t shift.
4. Reinforce seams with quality packing tape, especially along the main flaps.
5. Pick orientation: side-loading boxes make it easier to slide in delicate, elongated pieces.

These steps can help reduce movement and improve protection, but results may vary with item shape, fragility, and carrier handling.
