Bol Shipping Costs: Your Pack Size Counts Twice

At bol you pay for your pack size twice

Bol shipping costs hang on a single number: the size class your packaging falls into. In the Logistics via bol rate card, the total fee per ordered item runs from EUR 2.75 for 3XS to EUR 7.33 for L. That already covers pick and pack, shipping, customer service and returns. VAT, commission and surcharges come on top.

That is half the story. The other half sits in the same rate card and gets overlooked structurally: bol charges storage per item per month, not per cubic metre. That storage runs from EUR 0.14 for 3XS to EUR 0.95 for L and is counted daily.

That is the whole decision. One size class down lowers two lines at once: the amount you hand over on every order, and the rent you pay every month on everything that has not sold yet. If sales are slow, the second line hurts more than the first.

Amazon works differently. There, going flatter buys you one line, and it is a matter of cents: we worked out earlier that two extra centimetres of box thickness costs 35 cents per order. At bol the same step is measured in euros, and the storage comes on top. For a Dutch brand running most of its volume through bol, pack size is the most expensive design decision there is. And the only one whose return you can calculate in advance.

How much difference does a bol size class make?

Bol publishes the size limits as a separate table, on the Logistics via bol rates page. Put it next to the fees and the ladder becomes visible:

Look at the jump from XXS to XS. The footprint does not change: both stop at the same 37.5 by 26 centimetres. Only the permitted thickness goes from three to five centimetres. Those two centimetres cost EUR 1.55 per order and lift monthly storage from EUR 0.15 to EUR 0.24 per item.

We saw exactly the same pattern at Amazon, where the envelope tiers all share one footprint too. Length and width do nothing as long as you stay inside the plane. Your entire optimisation sits in the third dimension.

The rest of the ladder runs unevenly. From S to M you pay seventeen cents more while your permitted volume more than triples, so there is actually room there. And at L there is a separate volume limit of 70 litres on top of the size, which means you can never fully use the maximum box dimensions in practice.

Run it with your own numbers. The worked example below uses only the fees from the table above, for a brand selling a thousand units a month and holding an average of two thousand units in the fulfilment centre.

More than twenty thousand euros a year, for two centimetres of thickness, on a product that stays otherwise identical. That is no longer an optimisation, that is a line on your profit and loss account.

The second rate card: items under EUR 16

Bol publishes not one but two regular ladders. For items with a selling price under EUR 16 a separate, lower rate card applies. The storage fees are identical; only the shipping component is lower.

What this table makes clear: the cheaper ladder does not soften the problem, it relocates it. On the cheap ladder the step from XXS to XS costs exactly one euro instead of one and a half, but that is still close to a third of the XXS fee itself. On a product selling for twelve euros ninety-five, that is a serious slice of your margin.

And here is a second effect few brands calculate. The moment your price crosses the sixteen euro line, through a price increase, a bundle or a variant with extra content, you shift to the more expensive ladder in one step. An item that sits just under it and falls in XS costs you 75 cents less in fulfilment than the same item priced a euro higher. You raise your price by a euro and hand three quarters of it straight back.

That is not an argument for staying under the line. It is an argument for putting the size class and the price threshold on the table together when you set your bundle strategy, instead of treating them separately.

Why three centimetres is the binding dimension, not 3.2

This is where Dutch brands consistently pick the wrong anchor. The best known packaging dimension in this country is the letterbox size, and it comes from the carrier. PostNL allows a letterbox parcel up to 38 × 26.5 × 3.2 cm and up to 2 kilos. DHL uses exactly the same dimensions for its letterbox parcel, but with a weight limit of 1 kilo. Most mailers in the Netherlands are drawn to that number.

Put it next to bol size class XXS and the gap shows up on every axis:

Half a centimetre shorter, half a centimetre narrower, two millimetres thinner. Design to the PostNL dimension and you end up with a pack that sails through the letterbox and lands one size class too high at bol. That costs you the XXS to XS jump of one and a half euros per order plus the higher storage, every month, for years, without a single notification about it.

So the practical rule is short: design to the XXS dimensions from the table above and keep the weight under one kilo. You then satisfy bol XXS, the PostNL letterbox parcel and the DHL letterbox parcel at once. One dieline, one print run, three channels. The strictest dimension is always the binding one, and in the Dutch market that is bol, not the carrier.

What happens if you make your packaging smaller?

Here is the trap the rate card says nothing about. Since 15 October 2024 bol measures per EAN rather than per partner. You can request a remeasurement, but at most once every three months per item.

More important is what happens when you actually change the pack. Bol spells it out: if an existing item gets a new pack with new dimensions and you want it stocked in the fulfilment centre, you request a new EAN and stop selling the existing item yourself. Bol states it applies a stricter policy here than the GS1 standard, because a small dimensional change affects its operation. And then the sentence that costs the most: the reviews on your old item cannot be transferred to the new one, because these are two different EANs.

A packaging reduction at bol is therefore not a correction. It is a relaunch. You start the new listing at zero reviews, with all the consequences for your position in the search results that come with it.

That does not make the decision worse, just different. Three things follow from it:

• Do it alongside a product change, not on its own. New formula, new variant, new colour: moments where you need a new EAN anyway. Fold the size optimisation into that instead of running it as a separate project.
• Calculate the payback including the lost reviews. The fee saving is exact, the review loss is not. But it is real and belongs in the same sum.
• Do it once, properly. You cannot shave off half a centimetre every quarter. Fix the target dimension before you start drawing and design inside it.

For brands still to launch this is good news: the best size decision costs you nothing at that moment. Only existing listings carry a price tag for fixing it.

The penalties nobody puts in a dieline

Alongside the size class runs a second cost line that rarely reaches a packaging brief: the delivery conditions. Bol charges fixed amounts for these, even when the shipment is processed normally.

The delivery conditions themselves sit in a public PDF and they hit the design harder than you would expect. Every item needs a GTIN barcode that can be scanned without unpacking the item, on a flat surface, firmly attached. If there is shrink wrap around it, the barcode goes on the outside. If the item carries a 'this side up' sticker, the barcode cannot be on the bottom.

And then the rule e-commerce brands break most often: if loose items are delivered inside an outer box, the item barcode of the product inside that box may never be visible on the outer box. If an outer box carries multiple multipacks, the multipack GTIN may not appear on it either.

In practice that means a beautifully printed outer box with the product EAN on it will jam the fulfilment centre. Precisely the kind of outer box brands have printed because it looks professional. So we treat barcode placement and outer box blanking as part of the print readiness check, not as a technical detail the printer will sort out. What else is required on a pack is covered in what belongs on your packaging.

Bol sells a free dieline library

There is no rate discount at bol for plastic free, overbox free or ship in own container packaging. The rate card only knows size, weight and category surcharges, plus two separate lines: a surcharge for special product categories and EUR 0.45 per item to have stock returned or destroyed. Sustainability is not a rate argument at bol. Anyone selling it as one is selling air.

What bol does do is sell packaging as a product. The pallet prices are published openly on the partner platform, excluding VAT:

Read that table not as a purchase list but as a dimensional library. These are the sizes the fulfilment centre is built around and whose price is already fixed. Design your primary pack so it fits within one of them and your client never needs a custom box: no cutting die, no minimum order, no extra stock position.

Pay attention to the envelope box in the table above. At 38 by 26 centimetres it sits half a centimetre above the bol XXS footprint, because it is meant as an outer box rather than as your primary pack. So design your pack to lie flat inside it and stay within the XXS dimensions on its own. You then land in the second cheapest size class without needing a cutting die made. That is one of the few places where logistics hands you a design frame instead of a restriction.

What changes when you ship yourself?

For brands selling through their own webshop alongside bol, a second cost model runs in parallel. PostNL publishes its full 2026 rate card, tiered by annual volume:

Those numbers come straight from the PostNL business rates page. The tiers of the two options do not line up exactly, but the gap between a parcel and a letterbox parcel+ standard stays above three euros forty at every volume. That is a bigger gap than any size class jump at bol, and it hangs on those same three centimetres.

Something extra arrives in the autumn. From 15 November through 31 December 2026 PostNL charges a peak surcharge of EUR 0.32 per parcel and EUR 0.18 per letterbox parcel+.

Bol does the same in those months, but on storage: in November and December a peak rate of +40% applies to storage costs for all size classes from 3XS through 3XL.

Another reason to take that monthly storage seriously: stock sitting in the fulfilment centre for more than 180 days carries a surcharge of 100% on the regular storage rate. The two do not stack: in November and December only the long standing stock surcharge applies, not the peak rate as well. But for an L item that sits still, the storage line simply doubles.

DHL publishes no public rate ladder; there you request a quote. What DHL does publish are the dimensional limits: alongside the letterbox parcel, a standard parcel allows a longest side of up to 120 centimetres, other sides up to 60 centimetres, up to 20 kilos and a maximum of 240 litres. More generous than bol on every point. So the conclusion is the same as with Amazon and PostNL: the carrier is never your design frame.

How to run the numbers before you start drawing

A packaging brief that starts with the dimension looks different from one that starts with a moodboard. Five steps, in this order.

One: fix your channel mix and your strictest channel. If you sell through Logistics via bol, bol is binding. If you also sell on Amazon it becomes mixed per axis: bol is stricter on the footprint, Amazon on the thickness. If you sell only from your own webshop, the letterbox dimension leads.

Two: measure the product, not the current box. The real external dimensions including cap, protruding parts and the orientation in which the product lies flat. Many products are flatter than their packaging suggests, because that packaging was once built around the wrong axis.

Three: pick your target size class and work backwards. Fix the fee you want to land on and work back to a maximum closed external dimension, with margin for the closure. That number is the hard constraint for the rest of the design.

Four: budget the build up in the third dimension. Material thickness, insert, sleeve, closure, leaflet: add up what each element contributes to thickness. Whatever does not fit has to be solved flat. Printing on the inside of the flap instead of tissue paper. A die cut cardboard holder instead of foam. A QR code on the inside instead of a loose card.

Five: calculate the annual line and set it against the design budget. Shipping fee times annual volume, plus storage fee times average stock times twelve. That is the amount a redesign is allowed to cost. In most cases we see, it is not a close call.

Only after that do colour, typography, material and finish come in. They get all the room they need, inside a shell whose cost is already fixed. That is a different order of operations, not a smaller one.

Where we start a packaging project

In six years of Oase Creative we have guided more than 200 brands on bol, Amazon and Shopify. In nearly every packaging project that comes in, the dimension is already locked: by the printer, by an existing cutting die, or by a moodboard that arrived before the arithmetic. Almost never by the channel where the money leaks away.

We reverse that order. The first thing we deliver in a packaging project is a dimension sheet: closed external size, external size including closure, internal size, material thickness, and the size class that produces on every channel the brand sells through. Only then do we start drawing. That tends to produce a sharper design than a blank sheet, because one hard constraint forces better choices than complete freedom. Our brand work for Castagnola showed that again.

What you also buy is coherence. One dimension for bol and your own webshop means one dieline, one print run and one brand image, instead of three versions that happen to share a sender. That is exactly what we covered in product content across channels, and it applies to a box just as much as to a product photo. How that investment pays back, we worked through earlier in what packaging design returns in e-commerce.

Want to know which size class you are in right now? Measure your ship ready pack at its thickest point and hold that number against the first table in this article.
