What size pill box do I need for blister packs and bottles?

How do I measure blister cards and pill bottles for a box?

Never size a carton from the nominal tablet count or the fluid-ounce rating printed in a bottle catalog. A 60-count capsule bottle filled with large 00-size herbal capsules is much taller and wider than a 60-count bottle filled with small coated tablets. Likewise, two 10-cavity blister cards can have completely different dome depths depending on whether they hold flat caplets or thick softgels. Set your filled bottle or stacked blister cards on a flat table with the folded insert leaflet positioned exactly where it will ride in production. Measure across the widest points using calipers or a steel ruler, then add your sliding clearance so hand packers or automatic cartoners can load the product without snagging the dust flaps. When you send those numbers for custom pill boxes, our structural team builds the exact board caliper allowance into your dieline automatically.

1. Length (L): the left-to-right width across the front face of the blister card or bottle.
2. Width (W): the front-to-back depth of the bottle diameter or the stacked blister domes.
3. Height (H): the vertical distance from the base to the top of the cap or upright blister edge.
4. Sliding clearance: add 1/16 to 1/8 inch on L and W, and 1/8 inch on H so top flaps tuck flat.
5. Leaflet allowance: add an extra 1/8 inch to W whenever a multi-fold paper outsert sits inside.

What are the standard inside dimensions for custom pill boxes?

Although every CubitPack order is cut to your exact millimeter or sixteenth of an inch with zero die charges, most OTC tablets, dietary capsules and daily vitamin packs cluster around nine proven inside sizes. Use the reference table below to benchmark your primary pack before measuring your actual production sample. Notice how blister cartons have a wide front face and a narrow front-to-back depth (such as 2.5 × 0.75 × 3.75 inches), which maximizes billboard space on pharmacy shelves while keeping the cards upright. Bottle cartons use a square footprint (such as 2.125 × 2.125 inches) unless an internal paperboard partition widens one axis to create a dedicated pocket for a folded leaflet or dosing spoon.

How do I size a box for foil-backed tablet and softgel blister cards?

Blister cards are semi-rigid sheets with sharp thermoformed corners that can catch on carton dust flaps if the length and height are cut too tight. Measure the flat PVC/foil card length and height first, then add 1/8 inch to both dimensions so the sheet drops straight down into the carton without bowing. Depth (width W) is where most blister sizing errors happen. A single blister dome for an oval caplet may stand 3/16 inch tall, and two cards placed back-to-back take 3/8 inch, but once you slide a folded 8-panel paper leaflet alongside them, the paper acts like a spring and pushes the front carton wall outward into a pillow shape. Allowing 0.75 inch of depth for one or two cards plus a leaflet, or 1.25 to 1.75 inches for three to six cards, keeps the front panel flat so your custom medicine boxes stack cleanly on retail shelves.

How do I size a carton for 100 cc, 150 cc and glass pill bottles?

Round pill bottles have two diameters to check: the cylinder body and the closure. On child-resistant push-and-turn caps or wide ribbed closures, the cap diameter can actually be 1/16 inch wider than the bottle base. Always measure both and use the larger number as your baseline for Length and Width. If your bottle packs alone, a square footprint with 1/16 to 1/8 inch clearance on each side keeps the bottle centered. If you include a folded leaflet or a desiccant packet outside the bottle, ask for a fifth-panel internal divider or increase the Length by 3/16 inch so the folded paper sits in its own channel instead of jamming under the bottle base. For heavier 150 cc to 250 cc amber glass bottles used in custom supplement boxes and custom vitamin boxes, pair that footprint with an auto lock bottom box so the base cannot pop open when lifted.

What size dispenser box fits a 30-day roll of daily pill packets?

Personalized vitamin brands and daily longevity packs often seal a morning or evening dose of 4 to 8 pills into connected strip sachets that wind into a cylindrical roll of 28 or 30 packets. Because the roll must unwind freely inside the carton as the customer pulls one pouch each morning through the bottom front slot, you should never size a dispenser box tightly around the wound roll. Coil a full 30-day strip of filled packets on your table without compressing it tightly, measure the natural coil diameter, and add 3/8 to 1/2 inch to both Width and Height so the roll turns with zero friction. Typical 28-day and 30-day sachet rolls use a 3.5 inch wide packet strip and fit comfortably inside a 4.25 × 4.25 × 5.25 inch or 4.5 × 4.5 × 5.5 inch dispenser box. We position the perforated pull door about 0.75 inch above the bottom score line so the bottom wall acts as a lip that keeps the coil inside while the next packet feeds forward.

1. Packet strip width: carton Length (L) should be 1/4 inch wider than a single flat sachet.
2. Coil diameter: carton Width (W) and Height (H) should be 3/8 to 1/2 inch larger than the loosely wound 30-day roll.
3. Pull-slot height: place the perforated tear window near the lower front face so gravity feeds the next pouch.
4. Base strength: use an auto-lock bottom so the dispenser sits flat on a bathroom or kitchen counter for a full month.

Why are pill box sizes always written as inside dimensions?

Paperboard has physical thickness, typically 16 pt to 24 pt (about 0.016 to 0.024 inch per wall), and folded dust flaps or internal dividers double that thickness along the top and sides. If you ordered by outside dimensions, the board caliper would eat into the interior cavity and your blister card or bottle cap would scrape on the way in. Quoting by inside Length × Width × Height guarantees that the usable space inside the crease lines matches your product. If your finished cartons must also pack into a master corrugated case or sit inside a fixed retail shelf pusher tray, share that outer constraint with your account manager and we will verify both the inside fit and the outside footprint on your proof.

What are the most common pill box sizing mistakes?

Nearly every misfitting pill carton comes from ignoring the leaflet thickness or measuring an empty sachet strip instead of a wound 30-day coil. Watch out for these five errors

1. Measuring blister cards without the folded leaflet. A multi-panel outsert adds 1/8 inch of springy depth that bows a tight carton.
2. Checking only the bottle base diameter and missing a wider child-resistant push-and-turn cap rim.
3. Sizing a 30-day sachet dispenser tightly around a compressed roll. Leave 3/8 to 1/2 inch of spin room so daily packets pull smoothly.
4. Swapping Length and Height on horizontal vs vertical blister cartons, which puts the tuck opening on the long side instead of the top.
5. Using a standard friction tuck bottom on heavy 200 cc amber glass pill jars instead of an auto-lock bottom.
