Quick answer

Specify a cardboard tube as diameter × height. Start with the product's widest point and overall packed height, then allow clearance for the product, any insert and the opening style. Big Tubes has 18 stocked diameters from 35mm to 150mm, and cuts the height to the agreed specification. The correct final size should always be confirmed from a physical product sample.

Start with the product, not the artwork

The most attractive tube will still disappoint if the fit feels loose, difficult to open or too tight to remove. Before choosing a diameter, measure the finished product in the form it will actually be packed. Include its cap, closure, protective sleeve, label, tamper seal and anything that will travel inside the tube.

For round products, record the widest outside diameter with callipers. For square, oval or irregular products, measure the widest point across every direction. For bottles, this is often the shoulder or cap rather than the glass body. For jars and candles, it may be the lid. For gift sets, measure the finished bundle or insert rather than each component separately.

Height is equally important. Measure from the base of the packed product to its tallest point, then decide whether the pack needs a finger clearance, an insert, crinkle fill or a reveal above the product. A tube that is too short can press against a lid; one that is unnecessarily tall can look under-filled and add material and freight volume.

Understanding diameter and height

Tube dimensions are normally written as Ø diameter × height in millimetres. For example, Ø76 × 130mm means a 76mm tube diameter and 130mm finished height.

The diameter describes the tube opening, while the height describes the vertical body length. Big Tubes uses a consistent 2mm wall thickness; the key design decision is the tube style: butt joint, telescopic or tin lid.

Allow practical clearance

Clearance is the deliberate space between the product and the tube. It makes packing realistic and makes the product pleasant to remove. The exact allowance depends on the product surface, insert and closure style, but these questions lead to a useful starting brief:

• Does the product need to slide freely, or will an insert hold it in place?
• Is there a fragile label, foil neck wrap or decorative cap to protect?
• Will tissue, a branded card, moulded pulp, foam or crinkle fill be added?
• Does the product need a finger gap at the top?
• Is the tube for a single product, a pair or a full gift set?

Avoid treating a nominal product diameter as the final tube diameter. The product may be slightly out of round, and secondary packaging can add millimetres. A sample test is the best way to validate the experience before approving production.

Big Tubes stocked diameters

The stocked diameters are 35, 41, 47, 54, 65, 68, 73, 76, 80, 81, 84, 90, 100, 108, 120, 135, 140 and 150mm. Heights are cut to the agreed product requirement.

As a practical reference, smaller sizes such as Ø35–54mm can work for slim cosmetics, candles or small products; Ø65–90mm often suits jars, standard candle vessels and many bottles; Ø100–150mm offers room for wider bottles, gift sets and bundled products. These are starting points, not guaranteed fits. The finished product and insert determine the final specification.

For large orders requiring a larger diameter, Big Tubes can quote for a bespoke format where new plates are required.

How tube style affects fit

A butt joint tube has a compact lid that meets the body at one joint. It is clean and efficient, but the clearance must still account for the lid and opening action.

A telescopic tube has a full-length lid that slides over the body. It creates a longer reveal and can suit premium gifting, but the final height should account for how the lid and body overlap.

A tin-lid tube uses a metal lid, usually tin. It gives a distinctive closure and is frequently selected for premium food-adjacent, gifting or lifestyle formats. The lid and its opening tolerances should be checked against the product sample.

A useful quote checklist

Send us the following to make a size recommendation faster:

1. Product type and a clear photo.
2. Widest diameter and complete packed height in millimetres.
3. Quantity required.
4. Preferred tube style: butt joint, telescopic or tin lid.
5. Any insert, fill or protective component.
6. The desired print finish and artwork status.

If possible, provide a physical sample. It lets the fit be assessed alongside the opening experience and final finish before a quote is approved.
