What Size Should PLU Labels Be for Fruit? A Practical Sizing Guide

Start With the Fruit, Not the Label

Measure the flattest usable area on the fruit. A small citrus fruit gives you much less room than a large mango or melon. The label should sit on a fairly flat area without wrapping around a tight curve.

Pull a sample of the actual fruit from the line, not the biggest piece in the bin. Your labels have to work across the whole size range you pack.

• Small fruit such as limes, kiwi, and plums need compact labels.
• Medium fruit such as apples, pears, and oranges give more room.
• Large fruit such as mangoes, avocados, and melons can take larger labels, but curve and texture matter more.

Consider the Skin Surface

Smooth skin takes a label easily. Waxed, dimpled, fuzzy, or rough skin does not. A label that is too large on a textured surface will not make full contact, and the edges lift.

If your fruit is wet, waxed, or cooled before packing, tell us. Adhesive choice and label size work together, and we can match both to your conditions.

• Smooth skin: more size options.
• Waxed or oily skin: keep labels modest and use the right adhesive.
• Textured or fuzzy skin: smaller labels with strong tack usually hold better.

Match the Size to Your Applicator

Hand application and machine application have different limits. Machines are built around a specific label width, roll core, and liner. If you apply labels by machine, the label has to fit what that equipment feeds. Send us the make and model and we will build the roll to suit.

• Hand application: the most flexibility in size and shape.
• Semi-automatic applicators: size is set by the machine's feed path.
• Inline machines: confirm label width, roll diameter, and core size before ordering.

Round, Oval, or Rectangle

Shape affects both how the label sits and how much information fits on it. Round and oval labels are common on fruit because they follow the curve of the skin and look clean. Rectangles carry more text but have corners that can lift on curved fruit.

If you need room for a PLU number, a country of origin, and a brand name, a slightly larger oval can be a better fit than a small round label crowded with text.

• Round: simple, tidy, suits small and medium fruit.
• Oval: more room for text with a curve-friendly shape.
• Rectangle: most space, best on flatter surfaces.

Leave Room for the PLU Number and Barcode

The PLU number must be easy to read at the register, and any barcode or DataBar must be large enough to scan and have clear space around it. Do not shrink a code just to fit a tiny sticker. A label that cannot be read is worse than no label.

Retailers publish their own labeling rules, so confirm what your buyer expects before you lock in a size. We design with those requirements in mind and send a proof within 24 hours so you can check legibility before anything is printed.

• Keep the PLU number large and high contrast.
• Give barcodes and DataBars their required quiet space.
• Check the retailer's requirements before approving a proof.

Food-Safe Materials Matter at Any Size

Because a PLU sticker touches the fruit, the adhesive should be rated for direct food contact. Our labels use FDA-compliant direct food contact adhesive, and the materials are food safe. Size does not change that requirement, so confirm it with any supplier you compare.

Order Samples and Proof Before a Large Run

The safest way to confirm size is to see it. We are a Florida manufacturer with more than 40 years in the label industry. Tell us your fruit, your equipment, and your retailer, and we will recommend a size and shape, then send a proof within 24 hours. We are open 8am to 8pm, seven days a week, so a question on a Sunday still gets answered.
