What size supplement box do I need for bottles, jars and stick packs?

What are the standard supplement box sizes by bottle capacity and format?

Supplement bottles are sold by internal volume in cubic centimeters (cc) rather than fluid ounces. A 150 cc bottle holds roughly 60 standard size-00 vegetable capsules, whereas a 200 cc bottle holds 90 to 120 capsules. However, two 150 cc bottles from different mold makers can vary by 2 to 4 mm in diameter depending on whether the profile is a tall slim cylinder or a squat wide-mouth jar, and whether it is molded in PET plastic or thick-walled amber glass. Use the reference table below to benchmark your starting carton size before measuring your physical sample. Every row lists the inside carton dimensions (length × width × height in inches) used for custom printed supplement cartons, including clearance for smooth hand or automated loading.

How do I measure a round packer bottle and child-resistant cap for a box?

When sizing a square folding carton around a round cylindrical bottle, length (left-to-right front width) and width (front-to-back depth) are equal. The single biggest trap is measuring only the smooth bottom wall of the bottle while ignoring the cap and neck ring at the top. On 75 cc, 100 cc and 120 cc bottles fitted with a 38-400 child-resistant push-and-turn closure or a ribbed flip-top cap, the outer knurled diameter of the cap is often 1.5 to 2.5 mm wider than the bottle shoulder. If you size the carton to the narrower bottle body, the top of the box bulges outward around the cap and the top tuck flap refuses to stay closed. Always measure both the bottle diameter and the outer cap diameter with calipers, take the larger of the two numbers, and add 1/16 inch (1.5 mm) for a snug hand-packed fit or 3/32 inch (2.5 mm) for high-speed automated cartoning lines.

1. Measure bottle body diameter across the base and check for any label seam or shrink-band bulge.
2. Measure outer cap diameter across the widest ribs of a child-resistant or flip-top closure.
3. Use the larger diameter + 1/16 in (1.5 mm) as both your inside carton Length (L) and inside Width (W).
4. Measure total vertical height from the table surface to the top of the sealed cap, then add 1/8 in (3 mm) for inside Height (H).
5. Add extra width or depth if you are slipping a folded consumer information leaflet alongside the bottle.

How do I size a box for 15 or 30 hydration, collagen or greens stick packs?

Single-serve powder stick packs (sachets) behave very differently from rigid bottles because powder settles toward the bottom of each flexible packet, making the lower half of the sachet plumper than the flat heat-sealed top fin. If you calculate box depth by multiplying the flat empty thickness of one foil wrapper by 30, the filled sachets will bow the front and back carton walls outward like a pillow. Instead, gather the exact number of filled stick packs that go into one retail unit (for example, 15 packets stacked in a single column, or 30 packets arranged in two side-by-side columns of 15). Stand the bundle upright on your desk and hold it together with light finger pressure: just enough to keep the packets neat without squeezing the powder flat. Measure the bundle width, front-to-back stack depth at the plumpest lower third, and stick height, then add 1/8 inch (3 mm) to each dimension so packets slide smoothly out of a custom dispenser box.

How much space do blister cards, leaflets and neck collars add?

Probiotics, digestive enzymes and daily AM/PM vitamin regimens are frequently packed in foil-on-foil or PVC/foil thermoformed blister cards. Unlike round bottles, blister cards are flat rectangles with raised dome cavities. To size a carton for multiple blister cards, stack the cards the way they will be packed (either face-to-back or nested face-to-face) and measure the combined stack thickness across the raised domes, plus 1/16 inch for a folded paper leaflet and 1/16 inch of loading clearance. If you are packing a narrow-neck glass bottle, a small 30 ml dropper bottle, or a tall slim vial inside a wider square carton so you have more room for front-panel branding, include a custom cardboard insert or an extended top dust flap with a die-cut circular neck hole. A die-cut dust-flap collar costs almost nothing extra because it is cut from the existing top side flaps of the carton, yet it locks the bottle neck dead-center so the container cannot rattle.

1. Folded package insert leaflet: add 1/16 in (1.5 mm) to carton depth so the paper slips in without catching on the bottle.
2. Extended dust-flap neck collar: needs at least 0.5 in of vertical space between the bottle shoulder and the top of the cap.
3. Separate corrugated or card partition: add 1/8 in (3 mm) per divider wall when bundling 2 or 3 bottles in one kit.
4. Dosing scoop allowance: if packing a plastic scoop beside a pouch or jar, measure the scoop bowl depth and handle length.

Can I use one supplement box size across multiple bottle SKUs?

Many growing supplement brands carry four to six core products: a 60-capsule probiotic in a 120 cc bottle, a 90-capsule multivitamin in a 150 cc bottle, and a 60-capsule herbal adaptogen in a 150 cc bottle. Ordering one shared 2.25 × 2.25 × 4.25 inch carton size across all 120 cc and 150 cc products, and using an extended top dust-flap collar to hold the slightly shorter 120 cc bottle steady, lets you combine your order volume and simplify co-packer line changeovers. When all your bottle cartons share the exact same outside footprint, your contract packager does not need to re-adjust the rails on their cartoner or case-packer between flavor or formula runs, and your retail shelf display trays fit every SKU uniformly.

What are the most common supplement box sizing mistakes?

A carton that is 2 mm too tight slows down co-packer filling lines, while a carton that is 5 mm too loose arrives dented. Check these five sizing errors before approving your dieline

1. Measuring the smooth bottle wall while ignoring a wider ribbed child-resistant cap that prevents the top flap from closing flat.
2. Sizing a stick-pack dispenser box from flat empty foil wrappers instead of measuring the plump lower third of filled powder sachets.
3. Ordering outside dimensions instead of inside dimensions, which leaves the interior cavity 1 to 2 mm too tight after board folding.
4. Forgetting to add 1.5 mm of depth for a folded consumer leaflet or dosing tracker card tucked beside the bottle.
5. Packing a heavy 250 cc amber glass bottle in a tall carton with zero top neck stabilization, letting the bottle slam against the top flap.
