Most product packaging design advice is written for a shelf. It talks about colour psychology, typography, visual hierarchy, and the three seconds you get to catch a shopper’s eye in an aisle. All of which is true, and almost none of which helps if your product never sits on a shelf because it goes straight into a van.
Designing packaging for a product you deliver is a different brief. The decisions that cost you the most money are made before any artwork exists: the dimensions, the board grade, the closure, and the way the package opens. Get those wrong and no amount of print fixes it. Get them right and the visual side becomes cheap.
This covers the elements in the order you should decide them, and it’s honest about where the returns stop. The broader picture (layers, material choice, cost per order) sits in product packaging for delivery.
The Bottom Line
- Decide dimensions first. UPS and FedEx bill domestic US parcels on length × width × height ÷ 139 when that exceeds actual weight, so an oversized box costs you on every order forever.
- Board grade is a specification, not a feel. A 32 ECT single-wall box is rated to roughly 65 pounds of contents; 44 ECT to about 95 (Cubit Packaging, retrieved 2026-11-10).
- How a package opens is a design decision, and it’s the one that produces the customer’s first impression. Orientation beats print.
- Print is the last and most optional element. One-colour print on a well-fitted box outperforms full-colour on a badly sized one.
- Write the brief before you call a supplier. Suppliers optimise for what you specify, and an unspecified brief gets you their standard box.

The six key elements of product packaging design
For a product that gets delivered, the design brief has six parts. They’re listed in the order the decisions should be made, because each one constrains the next.
- Dimensions — how big the package is, which sets your shipping cost and your material cost simultaneously.
- Structure and board grade — what it’s made of and how strong, which is set by the weight and fragility of the contents.
- Internal fitment — dividers, trays, cushioning, and the orientation of the product inside.
- Closure — how it seals, how it opens, and whether it shows tampering.
- Information — address, contents, handling, allergens, dates, disposal.
- Print and finish — colour, logo, any coating.
Shelf-oriented design guides run this list roughly backwards. That’s the single biggest difference between designing for retail and designing for delivery, and it’s worth internalising before you spend anything.
Worked versions of all six, by product type, are in our product packaging examples for delivery.
Sizing the box: dimensions, DIM weight, and the 139 divisor
Dimensions are the single biggest decision in packaging design because they’re billed twice: once in material and once in freight.
Both UPS and FedEx calculate dimensional weight for domestic US parcels as length × width × height in inches divided by 139, and bill the greater of dimensional and actual weight. A box that’s two inches oversized in all three directions can push a light order up a billing tier on every shipment you ever make with it.
Even on your own vehicles, where there’s no carrier bill, oversizing still costs. A bigger box needs more void fill, takes more van space per order, and reduces how many stops you can run before reloading.
How to size properly:
- Measure your five most common orders, not your largest one. Design the box around what you actually ship most.
- Allow roughly two inches of cushioning clearance per side for fragile goods, and much less for soft goods that need containment rather than protection.
- Carry three or four sizes rather than one. One size means paying for air on small orders and under-protecting large ones.
- Check each candidate size against the 139 divisor before ordering. It’s a thirty-second calculation that you’d otherwise pay for on every parcel for years.
A useful design constraint: aim for the smallest box that still allows a packer to assemble the order quickly. There’s a point where saving another half inch costs you a minute of labour per order, and labour is the cost that scales worst.
Board grade and structure: what ECT ratings actually specify
The Edge Crush Test measures how much compressive force a corrugated board takes on its edge before crushing. It’s the number your supplier can tell you and the number you should be specifying.
| Board | Rated contents weight | Typical use |
|---|---|---|
| 32 ECT single-wall (200# burst) | up to ~65 lb | Most ecommerce and local delivery orders |
| 44 ECT single-wall | up to ~95 lb | Heavier orders, taller stacks |
| 48 ECT double-wall | up to ~100 lb | Heavy or high-value goods |
| 51 ECT double-wall | up to ~120 lb | Industrial, long pallet stacks |
Source: Cubit Packaging, retrieved 2026-11-10. The National Motor Freight Classification’s Item 222 treats these as minimums tied to contents weight rather than suggestions, and double-wall construction costs roughly 30 to 40% more per box than single-wall.
Two things people get wrong here.
Specifying from the average order instead of the heaviest. Your board grade needs to handle your worst case, because that’s the order that fails.
Ignoring stacking. ECT measures edge compression, which is what matters when boxes are stacked: in a van, on a dolly, in a customer’s receiving area. A box that’s fine in isolation can collapse as the bottom of a stack of six.
Flute profile is the other structural variable. Larger flutes (C, B) give cushioning and stacking strength; smaller flutes (E, F) give a smoother print surface and a thinner wall. If print quality matters to you, that trade-off is where it gets decided, not in the artwork.
Closures, seals, and how a package opens
The closure does three jobs at once, and most design briefs only mention one.
It has to stay shut. For taped cartons that means the H-tape method, centre seam plus both edge seams on top and bottom. For mailer boxes it means a tuck-front with a locking tab, not a flap that relies on friction. For food containers it means a locking rim rather than a press-on lid.
It has to show tampering, where that matters. A seal across the opening that tears visibly when broken. A sticker on the top of a lid proves nothing, because the lid can be lifted without touching it. On delivered food this is close to standard practice and costs pennies, and we cover its specifics in food packaging for delivery.
It has to open well. This is the part designers routinely skip, and it’s where almost all of the customer impression gets made. A package that needs a knife is a worse package. A tear strip, a perforated opening line, or a tuck-front that lifts cleanly turns the opening into something pleasant rather than something to get through.
Design the opening deliberately, because the customer experiences it in the order you designed: outer closure, first view inside, product orientation. Which brings us to the element that costs nothing and does the most.
Designing the inside: fitment and orientation
Internal fitment is the cheapest premium-feeling design decision available, and it’s structural rather than visual.
Three principles:
The product shouldn’t be able to reach a wall. Cushioning goes between the product and every surface. If it can touch the box, it will.
Separate anything that can hit anything else. Dividers and cells eliminate impact between items. This is a design decision with a die-cut, not a packing instruction.
Decide which way up the product faces when the lid comes off. A molded tray or a shaped insert holds the item facing the customer. It costs nothing per order once the tray exists, and it does more for the unboxing moment than full-colour print does.
Fitment is also where sustainability shows up most honestly. Trays and dividers made from molded fibre or corrugated recycle with the box, while plastic inserts don’t, and the material options for each are compared in eco-friendly product packaging solutions.
Print, colour, and branding on shipping boxes
Print is the last element to decide and the easiest to overspend on. Here’s a reasonable scale of ambition for a business that delivers locally.
Free or near-free. Choosing a consistent box colour and a consistent tape. Printed tape on a plain kraft box gives you brand recognition at a fraction of the cost of a printed box, and you can change it without scrapping box stock.
Cheap. One-colour flexographic print on kraft. A logo, a web address, orientation markings. This covers the entire practical benefit of branded packaging for most local operations.
Expensive, sometimes worth it. Full-colour litho-laminated print. Justifiable when the package is photographed by customers, when you’re competing on gift presentation, or when the product category expects it.
Rarely worth it for local delivery. Specialty finishes: soft-touch coating, foil, spot gloss. These are shelf-competition tools, and your package isn’t competing on a shelf.
Two design constraints that override aesthetics. Print needs a smooth flute profile to look good, which means a structural compromise you should make knowingly. And any print has to leave clear, uncluttered space for the shipping label, because a label over artwork scans worse and reads worse.
One honest note on the return. McKinsey’s 2025 packaging survey of more than 11,000 consumers across 11 countries found a wide gap between stated preference and willingness to pay, with only 13% of US consumers said they’d pay a lot more for sustainable packaging (McKinsey, retrieved 2026-11-10). The same gap exists for premium presentation. People notice good packaging; most of them won’t pay a premium for it. Design accordingly.
Designing for the route, not the shelf
A handful of design choices only make sense once you think about the vehicle.
Stackability. Boxes that stack flat and square load more per van and crush less. Irregular shapes and tubes are a packing problem for whoever loads the vehicle.
Grip and handles. On heavy catering or wholesale orders, hand holes are a design feature that reduces drops and makes the delivery faster.
Orientation markings. “This side up” printed large on two faces is one of the highest-value things you can print, and it costs nothing extra on a one-colour run.
Label placement. Design a flat, unobstructed panel for the label. Labels over seams, over tape, or wrapped around a corner fail to scan.
Weather. Kraft is not waterproof. If packages sit on unsheltered doorsteps, either the primary packaging handles moisture or the outer needs a coating.
Time. The longest time any order spends in the van is the real design input, not the average. Specify against the worst stop on your worst route.
How to write a packaging design brief
Suppliers build what you specify. An unspecified brief gets you their standard box, sized for their convenience.
A workable brief fits on one page and answers these:
- What are the dimensions and weight of the five most common orders?
- What is the heaviest order the box must hold, and does it get stacked?
- What is the longest time an order spends in transit, and at what temperature?
- What is the failure mode you’re designing against: impact, leak, crush, temperature, or presentation?
- How does the customer open it, and what do they see first?
- What information must appear on the outside, and where does the label go?
- What’s the per-order budget for packaging, materials and labour together?
- What volume are you ordering, and what’s your realistic reorder cycle?
Take that to two or three suppliers and you’ll get comparable quotes on comparable specifications. Take a vague description and you’ll get three different boxes you can’t compare.
Frequently asked questions about packaging design
What are the key elements of product packaging design?
For a delivered product: dimensions, structure and board grade, internal fitment and orientation, closure, the information the package carries, and print. Decide them in that order, because each constrains the next and the early ones cost far more than the late ones.
How do box dimensions affect shipping cost?
Directly. UPS and FedEx bill domestic US parcels on the greater of actual weight and dimensional weight, where dimensional weight is length × width × height ÷ 139. Excess empty space is billed as if it were weight on every shipment.
What board grade do I need for my boxes?
Specify from your heaviest order, not your average. A 32 ECT single-wall box is rated to roughly 65 pounds of contents and 44 ECT to about 95, with double-wall at 48 to 51 ECT handling 100 to 120 pounds (Cubit Packaging, retrieved 2026-11-10). Factor in stacking, since ECT measures exactly the compression that stacking creates.
Is custom-printed packaging worth the cost for a local delivery business?
Printed tape on plain kraft gives most of the brand recognition for a small fraction of the price, and it’s changeable. One-colour print on the box is the next reasonable step. Full-colour and specialty finishes are shelf-competition tools and rarely pay back for local delivery.
Should packaging design start with the product or the shipping method?
With the shipping method, if the product is delivered. The dimensions, board grade, and closure are determined by how the package travels, and those are the decisions that are expensive to change later. Visual design adapts to them easily; they don’t adapt to visual design at all.
Where to start
Measure your five most common orders this week and check their current boxes against the 139 divisor. If any of them are paying dimensional weight for empty space, that’s your first design change and it pays back immediately.
Then ask your supplier for the ECT rating on everything you currently buy and compare it against your heaviest order. Those two numbers, a dimension and a board grade, settle most of what a packaging design brief needs to say, and they’re both available in an afternoon.
