Most LP shipping boxes (record mailers) are sized to cover a 12-inch jacket with a little extra room, often around 12.5 x 12.5 inches. Depth varies, and many offer multi-depth closures (for example, about 0.5" or 1") so you can adjust based on how many records or pads you include.

• Measure your stack: Jacket(s) + inner sleeves + any pads.
• Choose multi-depth mailers: Adjustable closures help reduce shifting.
• Add inserts: Corrugated pads can help reinforce and fill small gaps.
• For 7-inch records: Look for 7–7.5-inch square mailers designed for 45 RPM singles.

Checking dimensions in the product description and photos can help you match a mailer to your exact packing style.

Capacity varies by design. Many LP shipping boxes are multi-depth, which means they can accommodate different stack heights without excess space.

• Common ranges: Some mailers are designed for 1–3 or 1–4 records (including jackets). A few options are built for larger bundles.
• Consider thickness: Gatefolds and heavy sleeves add bulk. Measure your stack and compare to the listed depth.
• Reinforce as needed: Using corrugated pads or foam sleeves can help reduce movement.
• Don’t overstuff: Slight compression is normal, but forcing closure may strain corners.

If you ship frequently, you’ll also find multi-pack quantities on product pages—use filters to explore pack counts and availability for pickup or delivery.

It depends on the box type. Slim record mailers are tailored to snugly ship a few albums, while general shipping or moving boxes are better for storing and transporting larger quantities.

• For mailing a few LPs: Use dedicated LP mailers with adjustable depth.
• For moving collections: Choose standard or heavy-duty moving boxes sized so records stand upright with minimal wiggle room.
• Packing tips: Group records in sleeves, add dividers or pads, and fill voids to limit shifting.
• Label clearly: Mark contents and orientation. Avoid overstacking to reduce pressure on jackets.

Product listings include dimensions and strength ratings to help you pick the right style.

A few simple steps can help protect vinyl during shipping with LP mailers.

1. Prep the vinyl: Place the record in a clean inner sleeve. Removing the record from the jacket can reduce seam splits.
2. Reinforce: Sandwich the jacket(s) between corrugated pads or add foam pouches to limit edge and corner pressure.
3. Size the mailer: Use a multi-depth LP mailer adjusted to your stack’s height to minimize movement.
4. Seal well: Tape all seams (an “H” pattern can help) so the mailer stays closed in transit.
5. Optional labels: “Fragile” stickers may raise handling awareness, though results can vary.

These steps can reduce common issues, but outcomes depend on handling and conditions.

ECT stands for Edge Crush Test. A 32 ECT rating indicates the compressive strength of a single-wall corrugated box’s edge, which relates to how it resists stacking and side pressure.

• Common rating: 32 ECT is typical for many standard shipping boxes and light-to-moderate loads.
• When to go higher: For heavier items, taller stacks, or rougher conditions, consider higher ECT or double-wall options.
• Check specs: Product pages list dimensions, material, and strength ratings so you can match the box to your use case.
• Storage tips: Avoid damp environments and excessive stacking to help maintain box integrity.

Choosing a box strength aligned with your packing and handling needs can improve protection.
