Foam Lined Cardboard Boxes: Sizes, Prices & Where to Buy

Which Foam Lined Cardboard Box Size Should You Use?

The right size depends on what you're shipping. Globe Packaging's range covers three sizes: small (7x5x2"), medium (11x7x2"), and large (14x11x2"), each suited to a different product category.

If you're shipping compact jewellery or accessories, the small box keeps things snug and protected. The large is better suited to bulkier flat items, such as framed prints or gift sets. For most everything in between, the medium is the go-to.

Before going into each size, there's one thing worth understanding about how these boxes work. They use a shell-and-slide construction: the inner foam-lined tray slides out from the outer cardboard shell, you place your product inside, and slide it back in. No flaps, no tape needed on the inner tray. 

With that in mind, here's a breakdown of all three sizes, their dimensions, pricing, and what they're best suited for.

Foam Lined Cardboard Box Sizes

Small: 7x5x2" (181x120x49mm)

This is the smallest box in the range and the right choice for compact, high-value items that require secure protection without excess space. The 49mm internal depth, combined with 20mm foam on each side, gives you a snug fit for items up to roughly 9mm in their thinnest dimension once the foam compresses slightly.

Price

Small foam lined boxes are available at Globe Packaging, starting at £17.69 for 10 pieces. Affordable bulk options, such as 200 pieces (£228.00) and 1,000 pieces (£998.00), are also available, making it a cost-effective choice for businesses with regular dispatch volumes.

Best For

The small foam lined box is ideal for:

• Jewellery and watches

• Small electronic components or accessories

• Collectible coins or medals

• Cosmetics and fragrance samples

• Corporate gifts or promotional items

If your product is compact and fragile, this size keeps things tight and protected without paying for space you don't need.

Use a small foam lined cardboard box for storing and transporting delicate items like jewellery.

Medium: 11x7x2" (279x181x51mm)

The medium box is the most versatile size in the range. At 279x181x51mm, it handles a wide range of products that are too large for the small box but don't require the full footprint of the large option. The extra length and width significantly expand the use case.

Price

The medium foam lined box ranges from £25.95 for 10 pieces to £978.00 for 600 pieces. As with smaller sizes, bulk order quantities can significantly reduce per-unit cost, making this a practical choice for businesses dispatching multiple orders daily.

Best For

The medium foam lined box works well for:

• Sunglasses and eyewear

• Small framed photographs or artwork prints

• Tablet accessories and tech peripherals

• Candles and glass jars

• Stationery sets and gift bundles

It's the box most businesses end up ordering in the highest volume, simply because the dimensions match such a broad range of everyday products.

If you need to ship or move candles or glass jars, use a medium-sized foam lined cardboard box

Large: 14x11x2" (360x280x50mm)

The large box is the biggest in the range and still qualifies as a Royal Mail small parcel, which is a genuine advantage for businesses shipping bulkier flat items. At 360x280mm, the internal footprint falls between A4 and A3, making it a strong option for anything with a wide, flat profile. The 20mm foam lining on all sides keeps even larger items securely cushioned throughout transit.

Price

Pricing for the large foam lined box starts at £35.95 for 10 pieces, with bulk options ranging from £154.00 for 50 pieces to £726.00 for 300 pieces. For businesses ordering in volume, the per-unit cost can be reduced considerably, making it a scalable solution as your dispatch quantities grow.

Best For

The large foam lined box is best suited for:

• A4-sized documents, certificates, or prints

• Larger electronic devices or accessories

• Picture frames and decorative flat items

• Premium gift sets with multiple components

• Branded retail packaging for fashion accessories

If you're shipping anything that needs a full, flat, protected surface area, this is the size that delivers, without tipping your shipment into a more expensive postage bracket.

For transporting picture frames and decorative items, use a large foam lined cardboard box.
