Start with what you’re packing and how you’ll use it. This page includes 20x20 bases in several heights, from low-profile flats to tall, cube-style boxes.

• 2"–6" (flat): Suited for shallow, flat items that stack neatly.
• 8"–12" (mid-height): Helpful for lighter bulky items without going too deep.
• 15"–16" (large): Roomy choice for household goods that need extra space.
• 20" cube: A versatile pick for general moving and storage.
• 25"–40" (tall/wardrobe-style): Made for taller contents and hanging garments.

Measure your items, allow space for padding, and consider how you’ll stack boxes. Pair the height with an appropriate board rating (single- or double-wall) for the item’s weight and handling.

Both types are available on this page, and your choice depends on weight, handling, and stacking needs.

• Single-wall (often 32 ECT): A practical, lighter option for everyday moving and general storage where loads and stacking are moderate.
• Double-wall or higher strength (e.g., 48 ECT, 200/275 lb test): Added rigidity for heavier contents, frequent handling, or taller stacks during storage or transit.

Think about how far items will travel and where they’ll be stored. Heavier-duty boxes can offer more protection, but results may vary based on packing technique and contents. Whichever you choose, use quality tape and avoid overfilling to help maintain box integrity.

Flat 20x20 boxes (typically 2"–6" high) are designed for low-profile packing where you want a wide footprint without much depth.

• Ideal for: Flat or shallow items that stack in layers and benefit from a snug, low-height container.
• Packing tips: Add edge/corner protection as needed, cushion surfaces to limit shifting, and fill remaining space so contents don’t slide.
• Storage and shipping: These sizes can be convenient for organizing shelves and shipping shallow items; just confirm your item’s thickness and allow room for padding.

Always check the exact height listed to make sure your item fits comfortably with protective materials.

You’ll find both options here, so you can buy exactly what you need.

• Single boxes: Useful when you only need one specific size, such as a single cube or a single flat box.
• Multi-packs: Many listings offer bundles (for example, sets that may include 5, 10, 15, or 20 boxes) in various heights and strengths, convenient for moving or regular shipping.

Review each listing for the quantity, dimensions, and board rating. Availability of pickup or delivery can vary by location and inventory, so it’s a good idea to check options in your cart before checkout.

This page includes tall, 20x20 wardrobe-style boxes designed to keep garments upright during moves.

• Height: Look for taller 20x20 formats (for example, around 34"), which are sized for hanging clothing.
• What to check: Product details typically note the exact height, bundle quantity, and whether any hanging components are included.
• Use case: These can help minimize creasing compared with folding into standard boxes, though results depend on weight and packing method.

Before purchasing, measure your hanging items and confirm the listed dimensions so you have enough clearance. If you need accessories, review the product description to see what’s included.
