How many sizes a product gets made in is among the earliest decisions in production planning. That decision also determines who the product will be sold to.
Which segment does a size define?
A hundred grams: single person or trial.
Two hundred and fifty to five hundred grams: household consumption.
One kilogram: a small business.
Two kilograms and above: mid-sized and large businesses.
Change the size and the customer changes; that is the fastest way into a new market without changing the product.
| Size | Segment | Unit cost | Waste risk | Channel |
|---|---|---|---|---|
| 100 g | Trial, one person | Highest | None | Retail, online |
| 250-500 g | Household | High | Low | Retail |
| 1 kg | Small business | Medium | Medium | Wholesale |
| 2 kg+ | Mid-sized business | Low | Depends on handling | Wholesale |
| 5 kg+ | Large business | Lowest | High | Direct |
How does the unit cost curve work?
Packaging cost per kilogram falls.
Filling line efficiency rises.
Volume efficiency in transport improves.
Labelling cost stays fixed and spreads across a larger pack.
Those four together make a two-kilogram pack forty percent cheaper per kilogram than a hundred-gram one.
Why does waste work in the opposite direction?
Once a large pack opens, the clock starts.
Where consumption cannot keep up, the product spoils.
A small pack carries no such risk.
Waste can reverse the advantage in unit cost.
The right size is where unit cost and waste risk intersect, and that point differs for every customer.
How does the intersection get found?
The customer's daily consumption gets measured.
The shelf life after opening is known.
The two get multiplied, and the result gives the ideal pack size.
For a product used at two hundred grams a day with five days of life, a one-kilogram pack is right.
Without that calculation the customer either overpays or produces waste.
How does shelf life limit the size?
For short-life products a large pack carries risk.
For long-life products a large pack causes no trouble.
In sliced charcuterie that limit is four days.
In frozen product there is no limit; life continues in the freezer.
That is why two-kilogram packs are common in frozen product and rare in fresh charcuterie.
How does channel fit work?
Retail wants small sizes.
Wholesale wants large ones.
Online prefers medium sizes, since shipping costs enter the calculation.
Foodservice varies with the rate of consumption.
A producer wanting to sell into all four ends up making at least three sizes.
What does producing multiple sizes cost?
Every size needs its own packaging material.
Every size needs its own label design.
The filling line needs resetting.
The number of stock lines rises.
That cost climbs quickly as the number of sizes grows, and producers generally stay within three or four.
Which size gets discontinued?
The one with the lowest sales volume.
The one sitting too close to another.
The one that finds no channel support.
The one generating the most complaints about waste.
Discontinuing a size matters as much as adding one while getting decided far less often, and unnecessary sizes can stay in a range for years.
What purpose does a trial size serve?
A hundred-gram pack makes it easier for an unfamiliar customer to take a risk.
Its unit cost is high while the barrier to purchase is low.
After a first trial the customer moves to a larger size.
In new categories that size is critical.
In categories with low recognition, such as freeze-dried and gluten-free, the trial size becomes the main engine of growth.
How does a foodservice customer choose a size?
Daily consumption gets calculated.
The life after opening is known.
Storage capacity gets assessed.
The ordering frequency gets set.
Those four figures together give the right size; choosing the largest pack by looking at the price per kilogram is the most common mistake.
How does the size decision affect price perception?
In a small pack the total price looks low.
Even with a high price per kilogram the purchase decision gets easier.
In a large pack the total price looks high.
The advantage per kilogram goes unnoticed on the shelf.
That difference in perception explains the volume leadership of small packs in retail, and the requirement to display price per kilogram partly closes it.
Where is this decision heading?
As households shrink, the share of small packs rises.
In foodservice large packs hold their share.
Online is growing the medium size.
Concern about packaging waste favours large sizes.
Two opposing forces work at once, and the outcome moves towards greater variety in sizes.
Why does the size decision work differently in frozen product?
Frozen product carries no pressure from the time after opening.
Only the day's need gets taken from a two-kilogram pack of raw cookies.
The rest stays in the freezer.
That takes waste risk out of the size decision.
The result is that large packs are both cheap and safe in the frozen category, with no need for a small size.
How does pack size change the shelf life label?
In a small pack the life after opening usually covers the whole pack.
A large pack needs a separate statement about the time after opening.
Two different periods have to be written.
Customers mostly do not read that second period.
So giving that information prominently on the surface of a large pack is a design decision that directly reduces waste.
What does a one-kilogram butter pack solve?
Patisseries and bakeries use high volumes daily.
The time spent opening small packs accumulates as labour.
A one-kilogram pack removes that labour.
Stored in a fridge, the life is sufficient.
That example shows the size decision being a calculation about labour as much as cost.
Who buys a hundred-gram pastırma pack?
Single-person households.
A customer trying the product for the first time.
A household using small amounts at breakfast.
In a product with a high unit price a small pack keeps the total payment acceptable, and that is the only way to build volume in expensive products.
