Size Guides
There is no standard set of rigid box sizes. Learn how to measure, what changes the dimensions and how to brief a maker.
There is no industry-standard set of rigid box sizes. A rigid box is a set-up format built around one specific product, so nearly every order is custom-sized. The right dimensions come from measuring the filled, sealed product. Then you add insert allowance and choose a lid style. Ask "what does my product measure filled and sealed?" Don't ask "what sizes do you offer?"
Makers specify rigid box sizes by the inner cavity: the space your product occupies. Length is the longer side of the opening. Height runs from the floor to the rim. Our packaging glossary defines the other terms.
Outer size is bigger. Each wall is chipboard plus wrap paper. Board thickness runs from about 0.8 mm to over 3 mm, per Bologna's Packaging Design Innovation Lab. QinPrinting pairs 2 mm board with smaller boxes and 3 mm with large ones. So a 2 mm wall adds about 4 mm per axis, plus a little for wrap.
The most common error is measuring the product empty or unassembled. Measure it as it will ship. A jar with its lid, label and shrink seal is bigger than the bare jar. A kit with its trays assembled is bigger than its parts. Our how to measure a box guide walks through the technique.
Rigid box dimensions vary with the product, so any table here is a planning aid only. These bands are illustrative inner cavity sizes. They aren't a standard or an Easy Box Packaging size list.
Band | Inner L × W × H (mm) | Typical contents |
|---|---|---|
Small | 80–130 × 60–100 × 30–60 | Single vial, dropper bottle, cosmetic item |
Medium | 150–220 × 100–160 × 50–90 | Supplement starter kit, candle gift box, skincare duo |
Large | 240–320 × 150–200 × 80–120 | Multi-component healthcare kit, device plus accessories |
XL | 330+ × 200+ × 120+ | Subscription gift set, multi-vial kit, large candle set |
Treat these as a starting sketch. Your product sets the real numbers.
Five things move the final rigid box sizes of any project.
Inserts deserve a closer look. A snug cavity gets the fit allowance. The box interior then equals the insert's outside plus a small gap. Don't stack full clearance on top of a snug cavity. Our box insert types guide compares the options.
There is no industry-standard rigid box size. Rigid boxes are a set-up format built to contain a specific product, so every rigid box is effectively custom-sized. Correct dimensions come from measuring the filled and sealed primary container. Then account for insert type and lid style.
That's why stock lists mislead. A "medium" from one maker won't match another's. Easy Box Packaging's small rigid boxes page says compact boxes avoid a nominal stock size. Our rigid boxes range is made to order from 50 units. We don't publish a surcharge rule, so ask for a quote on your dimensions.
I'd start every rigid project from the product, never from a size menu. A box chosen from a menu usually ends up either rattling or too tight.
A few Easy Box Packaging products that fit what this article covers.
Gift Boxes
A rigid two-piece gift box with a lift-off lid for a single keepsake, bottle, or jar. Choose SBS or kraft paperboard, then size the base and any insert around the item so the finished presentation has the structure and finish the gift calls for.

Rigid Boxes
A 2 piece rigid box uses a separate base and lift-off lid to give a single product or compact set a stable presentation. Share the packed footprint, height, weight, insert needs, opening direction, print coverage, and finish preference so the structure can be reviewed around the actual item.

Rigid Boxes
Small rigid boxes give compact products a firm base-and-lid presentation without forcing a nominal stock size. The finished footprint is scoped around the packed item's length, width, height, weight, insert needs, opening sequence, printed panels, and shipping route.

Candle Boxes
Rigid candle boxes use a sturdy two-piece base and lift-off lid to present a jar or tin with a deliberate opening moment. The box, insert, board, print, and finish are sized around the vessel's widest point and full height, including the lid. Share the packed dimensions, quantity, artwork direction, and shipping route for a quote-ready specification.

Gift Boxes
Custom white rigid gift boxes made to order around one keepsake, bottle, jar, or similarly presentation-led product. The separate base and lift-off lid hold a clean silhouette while your artwork, paperboard choice, finish, and optional insert are reviewed around the actual item inside.

Candle Boxes
Custom luxury candle boxes are printed around the real vessel, lid, and opening experience rather than a generic carton size. Choose a folding carton, sleeve, or more substantial base-and-lid direction, then coordinate the insert, board, artwork, and finish around a jar, tin, or gift set. The result is a composed pack for retail, gifting, or a careful unboxing.
Request a QuoteCustom rigid box sizes take four steps.
Measure three units from different batches and use the largest. Caps and labels drift between lots. I've seen a perfect fit turn tight on a reorder for exactly that reason.
Lid style changes both the outer dimensions and how the box opens. Name it on the quote.
Overlap depth in rigid box sizes is a design setting your manufacturer chooses. I couldn't find a published standard for it. Too tight and the lid binds. Too loose and it rattles. Ask for a sample.
Start from the product, then pick the structure. A single candle in a jar suits a lift-off lid or shoulder-neck box. A multi-vial healthcare kit needs a compartmented insert. A subscription box with several items wants a larger cavity and a tray. For kit-style structures, see our custom healthcare rigid kit boxes and custom supplement box kits.
If you're unsure about fit, order a sample first. Packaging samples catch lid and tolerance problems before the full run. Our manufacturing page shows how we build.
Rigid box sizes always start with the filled, sealed product. Quote the inner cavity in millimeters. Add insert and lid allowances, then confirm the outer size on a sample.
Size bands and clearance figures are illustrative guidance, not a standard. Your manufacturer's specification governs.
Questions, answered
There is no industry-standard rigid box size. Rigid boxes are a set-up format built around a specific product. Dimensions come from the filled, sealed container plus insert and lid allowances.
Makers specify rigid boxes by inner cavity dimensions. The outer size is larger by the board thickness on each wall. For 2 mm board, that's about 4 mm per axis.
Yes. Rigid boxes are made to order around the product. Length, width, height, insert and lid style are all set per project. Easy Box Packaging rigid orders start from 50 units.
Measure the product filled and sealed, with labels and seals on. Add clearance and any insert thickness. Send the maker L × W × H in millimeters, plus photos of four sides.
Greyboard is classified by thickness, from about 0.8 mm to over 3 mm. QinPrinting uses 2 mm for smaller rigid boxes and 3 mm for large ones. Ask your maker for the board they'll use.
Empty or unassembled measurements miss caps, labels, seals and trays. The filled, sealed unit is larger. A box sized to the bare product often won't close.
Yes. A thermoformed tray or foam block takes up space, so the cavity shrinks around it. Size the box to the insert's outside dimensions, not the bare product.
Yes. A lift-off lid must be slightly larger than the base. A sleeve and tray are sized as two parts. Confirm lid style and lid depth on the quote.
For a new shape, yes. A sample shows lid fit, insert grip and tolerance before production. Tolerance varies by maker, so ask for yours in writing.
