Funko Pop Box Dimensions: The UK Guide to Sizing, Protecting and Shipping Collectibles
A standard 4 inch Funko Pop comes in a box measuring roughly 159mm x 114mm x 89mm, which is 6.25in x 4.5in x 3.5in. That single figure is what almost every protector case, display shelf and postal box on the market is built around. Put one inside a snug outer box of about 200mm x 155mm x 130mm and you sit well inside Royal Mail’s Small Parcel band, which caps at 45cm x 35cm x 16cm. The number that quietly decides your postage is that 16cm limit on the smallest side. A standard Pop clears it easily, but a 6 inch Super Sized Pop often does not, and that is where sellers lose money without realising why.
This guide gives the sizes in millimetres first, because that is what UK suppliers and couriers work in. It also does something the collector guides do not: it maps each Funko size class to the outer box you actually need, and then to the Royal Mail band that outer box lands in. Where the published sources genuinely disagree about a size, this guide says so instead of picking one and presenting it as settled.
What size is a standard Funko Pop box?
A standard Funko Pop box measures approximately 159mm tall, 114mm wide and 89mm deep. In inches that is 6.25 x 4.5 x 3.5, and the figure holds across every source checked for this guide, including toy retailers, protector manufacturers and rival packaging suppliers.
You will often see this quoted as 16cm x 11.5cm x 9cm, which is a rounded conversion rather than a measurement. The exact conversion of 6.25in x 4.5in x 3.5in is 15.87cm x 11.43cm x 8.89cm, so 15.9cm x 11.4cm x 8.9cm is closer to the truth. The difference is small, but it matters if you are working out whether a box will fit a shelf run or a postal band with only a few millimetres of headroom.
Worth knowing: the figure inside is not actually 4 inches tall, since most standard Pops stand around 95mm to 100mm, roughly 3.75in to 4in. The box is much larger than the vinyl because of the window, the moulded tray and the header space above the head. That is why a box built to the figure’s height would be useless, and why every protector on the market is sized to the box rather than to the Pop.
Funko Pop box sizes across the ranges
Funko does not use one box. The standard 4 inch line is the one people mean when they say “a Funko box”, but the wider catalogue runs from keychain size up to figures taller than a toddler.
Here is where the published figures actually sit, converted to millimetres, with an honest note on how solid each one is.
| Funko range | Figure height | Box size, approximate (mm) | In inches | Confidence |
|---|---|---|---|---|
| Pocket Pop / Mini | 25mm to 38mm | 127 x 102 x 76 | 5 x 4 x 3 | Good. Sources agree. |
| Standard (4 inch) | 95mm to 100mm | 159 x 114 x 89 | 6.25 x 4.5 x 3.5 | Strong. Every source checked agrees. |
| Super Sized (6 inch) | approx. 150mm | 205 to 229 tall, 140 to 165 wide, 114 to 166 deep | 8 to 9 x 5.5 to 6.5 x 4.5 to 6.5 | Weak. Sources disagree by up to 50mm. |
| Jumbo (10 inch) | 250mm to 260mm | 330 tall, 203 to 229 wide, 152 to 216 deep | 13 x 8 to 9 x 6 to 8.5 | Mixed. Height agrees, width and depth do not. |
| Mega (18 inch) | approx. 450mm | 500mm+ tall, rest unconfirmed | 20in+ tall | Poor. No reliable published figure. |
| Deluxe, Rides, Moments, 2 packs | Varies | No single size exists | Varies | Not applicable. Measure yours. |
Two of those rows deserve more explanation than a table gives them.
The 6 inch Super Sized row is the messiest in the whole category. One widely copied figure puts the box at 229mm x 165mm x 140mm. Another supplier guide puts it at 205mm x 144mm x 166mm. A third puts it at 216mm x 140mm x 114mm. Meanwhile a protector manufacturer sells a 6 inch case built to fit a box of roughly 203mm x 165mm x 140mm.
Those are not rounding differences but genuinely different boxes, which almost certainly reflects the fact that Super Sized Pops vary a lot more in shape than standard ones do. If you are buying protectors or postal boxes in bulk for 6 inch Pops, measure the boxes you actually hold rather than trusting any published number, this one included.
The Mega (18 inch) row is one this guide will not fake. Every source that mentions Mega Pops describes the box as “over 20 inches” or “varies by character” without publishing a real set of dimensions. No figure could be confirmed, so none is given here, and if you need to ship one the only reliable answer is to measure it yourself.
Do protector cases change the dimensions?
Yes, though by less than most people expect. A 4 inch protector case is built to internal dimensions of roughly 162mm x 118mm x 92mm, which is about 1.5mm of clearance on each side around a 159mm x 114mm x 89mm box. Add the wall itself, commonly between 0.38mm and 0.7mm depending on the grade, and a protected standard Pop measures roughly 163mm x 119mm x 93mm on the outside.
That is 4mm to 5mm added on each axis in total, which will not change your postage band on a standard Pop. It can matter on a tight shelf, and it definitely matters if you are lining twenty of them up in a row, where an extra 5mm each becomes 100mm.
For reference, the equivalent 6 inch protector runs to about 206mm x 170mm x 142mm and the 10 inch protector to about 330mm x 228mm x 212mm. That 10 inch figure is useful for a different reason: it sits at the top of the disputed range for the Jumbo box itself, which suggests the larger published Jumbo figures are the more accurate ones.
One honest note before you read on. All Custom Packaging makes custom printed boxes and does not sell acrylic or PET protector cases, so this section is here because collectors ask about it, not because we are selling you one.
What size outer box do you need to post a boxed Funko Pop?
Never post a Funko in a box that fits it exactly. The corners are the first thing to crush, and a crushed corner is exactly what collectors grade a box down for.
The working rule for a boxed collectible is about 20mm of clearance on each side, so 40mm added to each dimension. That sits between the two figures in our own guide to stopping parcels arriving damaged, which suggests 10mm to 15mm per side for sturdy items and 50mm per side for genuinely fragile ones. A Funko is an odd case, because the vinyl figure is not fragile at all and the printed cardboard box around it is the valuable part. That box is the thing you are really protecting.
The table below maps each Funko size class to the outer box it needs, and then to the Royal Mail band that outer box lands in. The suggested outers are the 20mm rule rounded up to the nearest practical box size, because stock boxes come in round numbers. The band limits are Royal Mail’s own published formats, set out in full in our Royal Mail and Parcelforce parcel sizes guide.
| Funko range | Pop box (mm) | Suggested outer box (mm) | Royal Mail band | Headroom on the 160mm limit |
|---|---|---|---|---|
| Pocket Pop / Mini | 127 x 102 x 76 | 170 x 140 x 115 | Small Parcel | 45mm spare |
| Standard (4 inch) | 159 x 114 x 89 | 200 x 155 x 130 | Small Parcel | 30mm spare |
| Standard, in a protector | 163 x 119 x 93 | 205 x 160 x 135 | Small Parcel | 25mm spare |
| Super Sized (6 inch), slimmer boxes | 216 x 140 x 114 | 256 x 180 x 154 | Small Parcel | 6mm spare |
| Super Sized (6 inch), deeper boxes | 229 x 165 x 165 | 269 x 205 x 205 | Medium Parcel | 45mm over |
| Jumbo (10 inch) | 330 x 229 x 216 | 370 x 270 x 256 | Medium Parcel | 96mm over |
| Mega (18 inch) | Unconfirmed | Measure yours | Likely beyond Royal Mail Medium | Not applicable |
Royal Mail’s Small Parcel band allows up to 45cm x 35cm x 16cm and 2kg. Medium Parcel allows up to 61cm x 46cm x 46cm and 20kg. A parcel has to satisfy every one of those limits, so a single dimension going over pushes the whole parcel into the next band and the next price.
This table is worth sanity checking against what UK sellers actually buy. Purpose made Funko postal boxes sold in the UK cluster around 220mm x 160mm x 100mm and 175mm x 140mm x 135mm, with one commonly sold option at 290mm x 208mm x 95mm. All three sit inside Small Parcel and all three are close to the standard row above, so the maths and the market agree.
Why does a 6 inch Funko Pop cost more to post?
Look again at the Super Sized rows, because that pair of rows is the whole story of Funko postage in the UK.
Royal Mail’s Small Parcel band has a 16cm limit on the smallest dimension, and that limit is far tighter than the 45cm and 35cm limits on the other two. For a standard Pop it is irrelevant, because your outer box is only about 130mm on its smallest side. For a 6 inch Super Sized Pop, the Pop box alone can already be 165mm deep, which is over the limit before you have added a single sheet of packing paper.
So the 6 inch Pop is the size class where your packing decisions change your postage price. If your Pop box happens to be one of the slimmer 114mm deep variants, a snug outer at 154mm keeps you in Small Parcel with 6mm to spare. Add a generous layer of bubble wrap on the two large faces and you tip into Medium Parcel. Same figure, same protection level in the buyer’s eyes, higher postage on every single order.
That is the argument for a right sized box rather than a generous one. Three practical consequences follow:
- On 6 inch Pops, put your cushioning on the long faces and keep the smallest dimension as tight as the protection allows.
- Measure the actual boxes in your stock rather than working from a published Super Sized figure, since those figures disagree by up to 50mm.
- If you ship 6 inch Pops in volume, a custom outer sized to your specific stock is often cheaper over a year than the postage band you fall into with a generic box.
One caveat: band creep is never a reason to under pack. A parcel that arrives with a crushed box costs you the sale, the return postage and the review. Get the protection right first, then trim the outer down to the smallest size that still delivers it.
How to pack a boxed Funko so the box survives
The order of operations matters more than the materials.
Start by protecting the printed faces of the Pop box itself, not the figure. A soft sleeve or a hard protector does that job, and collector guidance generally suggests a soft protector on anything worth keeping and a hard case on higher value pieces. Then wrap the protected Pop so nothing touches the outer wall directly.
Only then do you choose your outer box, which is the box in box approach, and our protective packaging guide covers void fill types and sealing technique in detail, so this guide will not repeat it.
Two Funko specific points that guide does not cover:
Corners take the impact, so pad the corners. Every collector grading scale treats corner sharpness as the headline condition marker. Void fill spread evenly through a parcel protects the middle of the faces and leaves the corners exposed, so concentrate your cushioning at the eight corners of the Pop box.
Do not let two Pops touch. If you are sending more than one, each needs its own wrap or a divider between them. Two boxed Pops rubbing together in transit will scuff each other’s print even when the outer parcel arrives undamaged.
If you are unsure whether you need a mailer or a plain shipping box for this, our mailer box versus shipping box guide sets out what each layer is actually for.
How do you measure a Funko Pop box correctly?
Published figures are a starting point, but your own stock is the real answer, and Funko changes its packaging between waves.
Measure the external dimensions of the Pop box, because that is what a protector or an outer box has to swallow. Measure the internal dimensions of any outer box you are quoting, because that is the usable space. Confusing the two is the single most common measurement error we see on enquiries, and our guide to measuring length, width and height explains why wall thickness makes them different numbers.
Three habits that save reprints:
- Measure three boxes from the same wave rather than one, because cardboard varies between print runs.
- Include any lid flap or tab that sticks proud of the face, because it counts towards the outer box you need.
- Record everything in millimetres, because converting inches to centimetres and rounding is how a 158.75mm box becomes a 160mm box on a spec sheet, and how a snug outer becomes a tight one.
For UK resellers shipping collectibles at volume
If you ship a handful of Pops a month, buy a stock postal box in one of the sizes above and move on, because the maths only changes once you are shipping hundreds.
At volume, a generic box costs you twice over: you pay for the void fill that makes up the difference between the box and the Pop, and you pay the higher postage band when that void fill pushes a dimension over a limit. A box sized to the product you actually ship removes both costs at once, and it does it on every order for as long as you sell that product.
A custom mailer box sized to a standard Pop, printed inside and out, also turns the outer packaging into part of the unboxing rather than something the buyer bins. For heavier multi Pop orders or Jumbo figures, a double wall shipping box is the sturdier route, and the two do different jobs.

Frequently asked questions
How big is a standard Funko Pop box? A standard 4 inch Funko Pop box measures approximately 159mm x 114mm x 89mm, which is 6.25in x 4.5in x 3.5in. The commonly quoted 16cm x 11.5cm x 9cm is a rounded conversion of the same figure.
What size box should I use to ship a Funko Pop in the UK? For a single standard Pop, an outer box of roughly 200mm x 155mm x 130mm gives about 20mm of cushioning on each side and stays inside Royal Mail’s Small Parcel band. Purpose made UK Funko postal boxes sold at 220mm x 160mm x 100mm and 175mm x 140mm x 135mm sit in the same range.
Does a Funko Pop fit in a Royal Mail Small Parcel? Yes. A standard 4 inch Pop in a suitable outer box measures around 200mm x 155mm x 130mm, comfortably inside the Small Parcel limit of 45cm x 35cm x 16cm and well under the 2kg weight cap. A Jumbo 10 inch Pop does not fit and needs Medium Parcel.
What are the dimensions of a 6 inch Funko Pop box? Published figures disagree. They range from roughly 205mm to 229mm tall, 140mm to 165mm wide and 114mm to 166mm deep. Measure your own stock rather than relying on a single published number, because that 50mm spread is enough to change your postage band.
Do protector cases change the box size? Only slightly. A 4 inch protector adds 4mm to 5mm across each axis in total, giving an outside measurement of about 163mm x 119mm x 93mm. That will not change your Royal Mail band, but it adds up across a shelf of twenty.
What size is a Jumbo 10 inch Funko Pop box? Around 330mm tall. Published width and depth figures range from 203mm to 229mm wide and 152mm to 216mm deep. A 10 inch protector case measuring about 330mm x 228mm x 212mm suggests the larger end of that range is the more accurate one.
Why do Funko box dimensions vary between figures in the same range? Capes, wings, weapons, vehicles and display bases all need extra depth or width, and special editions sometimes use different board or a deeper moulded tray. Funko keeps the standard 4 inch box consistent, but larger and speciality ranges vary by character.
Key takeaways
- A standard 4 inch Funko Pop box measures approximately 159mm x 114mm x 89mm. The widely quoted 16 x 11.5 x 9cm is a rounded version of the same number.
- Post a standard Pop in an outer of about 200mm x 155mm x 130mm and you stay inside Royal Mail’s Small Parcel band with room to spare.
- The 16cm limit on a Small Parcel’s smallest dimension is the number that decides your postage, not the length.
- The 6 inch Super Sized Pop sits right on that limit, so packing decisions on that one size class change what you pay on every order.
- Published 6 inch and Jumbo figures disagree by up to 50mm between sources. Measure your own stock before buying protectors or postal boxes in bulk.
- No reliable published dimensions exist for Mega 18 inch Pops, so measure your own before you buy anything to ship them in.
