This belt is from the till in our shop and stretched.. It's 31 years old so finding a new one is tricky.
3mm wide but needs to be exactly the right length. Where should I start my search?
Googling just throws up timing belts.
Belts usually have a code printed on them related to length, width, tooth pitch etc. Anything like that? If not I'd probably search for the till model plus 'belt' or 'tooth belt' to either find a supplier or the specification of it. An AI search might help too.
Our local bearing supplier, part of a chain now, Acorn? Has always supplied belts too - might be worth a look.
Also Dansies, Chesterfield, used to do till repairs but moved into photocopiers- they use lots of belts so there might be an identical one. Good luck!
I would start by marking the belt at every 10th tooth to make it easier to count how many there are correctly.
Then using the marks work out what the pitch ot the belt is, so any multiple of 10 teeth measured from the same part of the profile then decide that by the numbers of teeth you have measured will give you the pitch.
Can you measure the centres between the shafts it runs on, (or the distance from outer and outer sided of the pulleys) the diameter of the pulleys and number of teeth on each? This would be helpful for a belt supplier to get you the correct belt.
I haven't used them for many years but HPC gears used to be helpful, Google should give you local mechanical parts suppliers some will be specialist in belts and gear.
Have you googled the parts diagram for the till?
Tills are very common and till servicing is definitely a thing so there will be a service manual and spec on the internet somewhere. Or the manufacturer will have the parts spec etc.
As above by K. Then have a look on the RS website. You may find something, if not it will give you an idea of roughly what you're looking for.

Do the pulleys have teeth, as that pic looks more like a cogged* Wedge/V belt, rather than a toothed belt.
Smallest industrial size is Z section (about 3/8"/8mm wide IIRC), but I have no idea what standards are smaller than that, and a quick google suggests you're into the realm of fairly specialised belts.
In a pinch, a suitably sized O-ring would likely work.
If it is a toothed belt, the first step is measuring the tooth pitch, and figuring out if it's metric or imperial.
Imperial belt pitches are depicted by letters, metric simply by stating the pitch size, however metric also come in varying teeth profiles, but on something like a till, I doubt they'll make much difference to performance provided the pitch matches.
Then when you know the pitch, you just need the number of teeth to get the right size.
*the "teeth" on cogged belts are there to give the belt more clearance so it can flex around smaller diameter pulleys, while still maintaining belt height so it isn't likely to flip over in the pulleys.
You may be correct with it being a vee belt, I think I miss read and mistook it as how to find the correct timing belt.
Vee belts don't have to be a Vee profile if the loads are low.
I've had success making my own length wedge belts that I can't get the correct Vee belt using polyurethane cord and heat splicing to the correct length. Basically like an "O" ring.
So measuring, again you can mark the belt with a start position and press it flat on a ruler or tape moving it along till you get back to the mark. Bit of guessing work and get somewhere near the length you need.
So we are just all smoothing over my obvious suggestion in favour of guesswork and measurements?
Are you new here?

I think most people would have assumed that had already been done, because, as you say, it is obvious (but worth mentioning).
Not sorted yet but I will phone some of the companies mentioned and will send the belt to them (we have another stretched spare).
Fine. I will do it.
What is the make model of the till
While you are at it would you find me a 717J8 belt in the UK please?
The till is a Geller NT2108
Hurty washing machine?
Well, it’s starting to squeak a bit with a heavy load so best to have a belt at the ready. Thanks for the link, I actually used it and placed an order 👍
Its probably this. Geller is a bit vague but they seem to be a samsung/ sam4s clone.
Journal take up belt search may give you more specific results but frankly i think i have made my point 🤣
Update. Geller is discontinued. I would bet it fits though and geller bought in a samsung heat printer component.
Christ i am bored.
The rpinter will be an epson (geller Samsung etc all use the same printer thats why they are likely to be interchangeable) look over the printer unit and you will probably find epson followed by a code. And THEN you will be cooking with gas.
