Start with what you’re packing, then match size and strength.

• Small boxes (around 17×11×12) can work for books, tools, and canned goods so weight stays manageable.
• Medium boxes (about 18×14×12 or 22×13×15) are versatile for kitchen items, decor, and toys.
• Large/X‑large boxes (27×15×17, 23×23×16) suit bulky, lightweight items like bedding and pillows.
• Specialty sizes such as long or tall boxes (e.g., 4×4×36, 12×12×48) can help with posters, lamps, or rods.
• Strength: Look for mentions like “heavy duty,” an ECT rating (e.g., 32), or “200 lb test” for added durability.

Fill gaps with soft items, keep boxes liftable, and label sides. Ordering online for pickup or delivery can make it easier to get the mix you need.

In this category, a “cardboard box” usually means a corrugated shipping or moving box. It’s made from layered paper: two flat liners with a fluted layer in between for strength and cushioning. Most options here are single‑wall corrugated, offered in many dimensions for moving, storage, or mailing.

• Ratings may appear on the box or product page, such as an ECT (Edge Crush Test) number or a 200 lb test burst rating. These indicate how sturdy the box is.
• Use cases range from small mailers (e.g., 6×6×6) to large moving boxes (e.g., 27×15×17), as well as long or tall boxes for specialty items.

Choosing by size and strength can help match the box to your packing needs.

ECT stands for Edge Crush Test, a measure of how much stacking pressure a corrugated box can handle on its edges. It’s a common way to describe strength for moving and shipping boxes.

• ECT 32 is a typical rating for many household packing needs and general shipping.
• Higher ECT numbers or mentions of “heavy duty” can indicate added durability for heavier or more delicate items.
• You may also see a 200 lb test (burst rating), another method of describing box strength.

Consider the item’s weight and how boxes will be stacked. Matching the rating to your use case can help reduce crushing risks. If you’re unsure, check the product details for both dimensions and strength information before ordering.

A few simple choices can help stretch your budget without sacrificing usability.

• Buy in multipacks: Look for 10‑, 20‑, or larger count boxes on the page for convenient bulk ordering.
• Mix sizes strategically: Use small boxes for heavy items and large boxes for light, bulky items to avoid overpacking.
• Measure first: Matching box dimensions to your items helps reduce void fill and the number of boxes needed.
• Choose the right strength: Standard ECT ratings can work for most household goods; reserve heavy‑duty for truly heavy or fragile loads.
• Use pickup or delivery: Ordering online for pickup or delivery can save extra trips and time.

These steps can help you get the right mix without buying more than you need.

Pick a snug, sturdy size and a suitable strength for your item.

• Cube mailers like 4×4×4, 6×6×6, or 8×8×8 can work for compact gadgets, candles, or mugs.
• Shallow mailers such as 6×4×3, 9×6×4, or 12×10×4 often fit accessories, beauty items, and folded apparel.
• Long boxes (e.g., 4×4×36) help with posters, rolled prints, or rods.
• Strength: Standard ECT options suit lighter goods; consider heavy‑duty picks when shipping fragile or heavier items.

Wrap items, add appropriate cushioning, and tape seams along all edges. Choosing sizes close to your product’s dimensions can reduce shifting without excess fill. You can order online for quick pickup or delivery when you need to restock.
