“Medium” can cover different use cases, so sizes vary across moving, shipping, and mailer boxes. Common examples you’ll see include:

• Moving boxes: about 18 x 14 x 12 in, 18 x 18 x 16 in, and 22 x 13 x 15 in.
• Shipping/mailers: around 12 x 10 x 10 in, 11 x 7.5 x 5.5 in, and 10 x 8 x 5 in.

Dimensions may be listed as internal or external, and availability can change.

• Check the product description for exact measurements.
• Match the size to your items and cushioning.
• If you’re unsure, measure your item and add 2–3 inches.

Prices for medium boxes can vary based on several factors:

• Board strength: ratings like ECT and single vs. double-wall construction.
• Dimensions: larger boxes use more material.
• Features: handles, lids, specialty colors, and finish details.
• Pack size: multi-packs may lower the per-box cost.
• Fulfillment: delivery vs. pickup can influence overall totals.

To compare, browse listings on Walmart.com, use filters (Size, Strength, Pack Count), and review the per-box value in bundles. Availability and promotions can change, so checking current product pages is helpful.

Medium moving boxes are versatile for everyday household items, as long as you avoid overloading.

• Kitchenware: dishes, pantry goods, small appliances—use padding.
• Books: mix with lighter items to manage weight.
• Linens, toys, decor, office supplies and similar items.
• Electronics accessories: cables and peripherals (avoid delicate screens).

Helpful steps include cushioning gaps, taping seams, and labeling contents and destination room. Check the box’s listed weight guidance and distribute weight evenly. Heavier boxes typically go at the bottom when stacking, but results can vary by contents and box strength.

Medium boxes at Walmart span a range because the label covers moving, shipping, and mailers.

• Moving: many are around 18 x 14 x 12 in to 18 x 18 x 16 in.
• Shipping/mailers: compact options like about 12 x 10 x 10 in or 10 x 8 x 5 in.
• Dimensions: check if listed as internal or external.

To pick the right size, measure your items, add 2–3 inches for cushioning, and confirm a strength rating that suits the load. Filters such as Size, Strength, and Pack Count can help narrow the selection on Walmart.com.

Medium boxes can work well for small business shipping, depending on your products and packing workflow.

• Select corrugated shipping styles with a suitable strength rating (e.g., 32 ECT).
• Choose a form factor: traditional RSC cartons or tuck-top mailers.
• Match dimensions to reduce void fill and help limit damage risk.
• Ensure surfaces accommodate labels and any branding inserts.
• Test sample shipments to confirm protection and packing speed.

Carrier size and weight rules vary, so reviewing them before scaling can be helpful. Walmart offers multi-pack options that can streamline restocking.
