What size box fits 4-pan, 6-pan, 12-pan and 35-pan makeup palettes?

How do I measure an assembled makeup palette for an outer carton or sleeve?

Whether your primary palette is an injection-molded acrylic case or a wrapped rigid magnetic book, small structural details change its true outer footprint. On a rigid book-style palette, the wrapped chipboard (gray board) cover often overhangs the inner pan deck by 1/16 inch on three sides, and the hinged spine can crown slightly thicker than the magnetic fore-edge. On a molded plastic palette, the rear hinge barrel and front clasp lip protrude past the main frame. Folding cartons and sleeves are always quoted by inside dimensions written as Length × Width × Height (L × W × H). For a wide rectangular palette, set the long horizontal cover dimension as Length, the thin spine depth as Width, and the vertical cover height as Height (or orient the tuck flaps on the narrow ends so the wide cover panels stay uninterrupted). When you quote printed makeup palette cartons, our prepress team verifies your caliper numbers and builds a 3D mockup before payment.

1. Measure total palette length and width across the outermost cover edges or hinge knuckles.
2. Measure thickness at both the spine and the front clasp when the palette is closed with its brush or mirror inside.
3. For a 6-sided straight tuck carton, add 1/16 in to width and depth and 1/8 in to the tuck-flap axis.
4. For an open-end slipcase sleeve, add exactly 1/16 in (1.5 mm) to spine thickness and vertical height for smooth sliding.
5. If adding an internal E-flute corrugated shock sleeve for large palettes, add 3/16 in to all three inside dimensions.

What are the standard makeup palette box dimensions by pan count?

Because CubitPack cuts every order to your exact dieline with zero die or plate charges, you can build around any custom pan arrangement, from a long narrow 5-pan contour bar to an octagonal holiday vault. Still, most face, cheek, lip and artistry palettes cluster around seven classic footprints. Use the reference table below to benchmark your palette size before measuring your physical sample. Notice how face palettes (which use wider 36 mm to 59 mm blush, bronzer and highlighter pans) have larger footprints per pan than eye or lip palettes (which typically use 20 mm to 26 mm pans). Every dimension listed in the chart represents the usable inside space of the outer folding carton or slipcase sleeve.

How do I calculate custom rigid book palette dimensions from pan sizes?

If you are engineering a custom wrapped rigid magnetic book palette from the ground up (starting at 50 units), your outer dimensions are driven by the metal pans inside. Standard round or square aluminum cosmetic pans come in 26 mm (1.02 in) for eye and lip colors, 36 mm (1.42 in) for cheek and highlighter trios, and 44 mm to 59 mm (1.73 to 2.32 in) for bronzers and setting powders. To calculate the width and height of the inner die-cut pan deck, sum the pan widths in each row and add 6 mm to 8 mm (about 1/4 inch) of paperboard bridge between adjacent pans so the die-cut web stays flat and leaves room for printed shade names beneath each well. Next, add a 12 mm to 15 mm (about 1/2 inch) perimeter rim around all four edges of the deck to house the concealed neodymium closure magnets and support the lid when closed. Pair your rigid book with precision custom cardboard inserts or custom EVA foam inserts to lock every pan flush.

How much thickness do internal mirrors, acetate shields and brushes add?

Founders often calculate palette length and width accurately from the pan grid but underestimate the closed spine thickness (Height or Width). A bare magnetic pan deck with a flat cardboard cover can be as slim as 0.45 to 0.5 inches thick. However, adding a 1.5 mm glass vanity mirror inside the top lid, a clear PET acetate dust sheet over the pans, and a recessed well for a dual-ended contour brush increases the spine thickness to 0.75 or 0.875 inches. If you also include domed baked highlighter pans alongside flat matte contour pans in the same face palette, size the well depth and spine height to clear the tallest baked dome by at least 2 mm so the clear dust shield and mirror never press down on the powder peak. If you sell individual cheek pans alongside your multi-pan palettes, see our custom blush boxes and custom eyeshadow boxes for single-pan and quad dimensions.

When should I expand the box size to fit a corrugated drop buffer?

Once a makeup palette exceeds 6 inches in length (such as an 18-pan artistry book or a 35-pan pro vault), the wide flat surface acts like a lever during parcel transit. If a heavy box lands on one corner of the palette in a sorting bin, diagonal torsional flex can pop pressed cakes out of their glue wells or crack the internal glass mirror across the middle. For any palette 6.5 inches or wider that ships direct-to-consumer, we recommend adding a wrap-around E-flute corrugated inner buffer inside your printed retail carton, or packing the retail carton inside a custom-fitted custom mailer box. Add 3/16 inch to your outer carton's length, width and height whenever you include an inner corrugated buffer pad.

1. Palettes under 5 inches (quads & 6-pan compacts): a snug folding paperboard carton or sleeve is sufficient for retail.
2. Palettes 6 to 8 inches wide with glass mirrors: add an internal folded card frame or E-flute buffer pad (+3/16 in).
3. Large 24-to-35 pan pro palettes: ship in a custom E-flute mailer box or foam-lined rigid collector case.
4. Order a physical prototype or paid printed sample (credited to your order) to drop-test your filled palette before production.

What are the most common makeup palette box sizing mistakes?

Wide flat palettes have tight sliding tolerances and fragile mirrors. Avoid these five sizing errors before approving your structural dieline

1. Cutting an open-end slipcase sleeve to the exact spine thickness of a soft-touch book palette with zero clearance, causing the sleeve to jam halfway on.
2. Measuring the inner pan deck of a rigid book palette and forgetting the 1/16 inch outer cover overhang around the three open edges.
3. Placing pan wells only 2 mm apart on a custom deck, which leaves the die-cut paperboard web too weak to stay flat and leaves no room for shade names.
4. Forgetting to add spine depth for a 1.5 mm glass mirror, clear acetate dust sheet or dual-ended brush cavity.
5. Shipping wide 18-to-35 pan palettes in a thin carton with no corrugated buffer allowance, leading to cracked mirrors in e-commerce transit.
