How can I identify the power rating (wattage) of my scavenged resistors?

I am currently making a mini guitar amplifier, from this instructable, https://www.instructables.com/id/Make-a-Sweet-Portable-Guitar-Amp/, and i need a 1kΩ resistor.

I have accumulated a few components by de-soldering and scavenging parts from old, and broken electronic devices.

When I found out i needed a 1kΩ resistor, I looked up the ring code for that value and scanned over my broken electronic circuit boards to see if i could find a match. Which i did, but i do not know how many watts the resistor is rated at.

The resistor in question is no more than 3mm in length. I know that quite a lot of resistors are more like 5mm in length.

Can you tell from the physical size what the resistor I have is?(I will include a couple of pictures)

Reckon on 1/8 W for the little one, and maybe 1/4 for the big ones.
this3 is3 als3o bothering me. es3pecially in televisions.. 3sometimes3 s3maller reis3tors3 s3eems to have bigger pow9er rating. w9hen compared to others
It depends on the materials of construction as much as the size. Small, well made ones, may run hotter than cheaper ones, without losing life - but you still have to be careful not to burn anything !!

ok, so if i need a 1/4 resistor i need to find one like the larger size to be safe?
Yes.

ok, anywhere easy to find these, maybe a common use i could scavenge one from. Cause I live in the UK and the only shop you can buy components from is Maplins (like radioshack) firstly which is very expensive and secondly i don't think they sell singular resistors.

Maybe i should buy a mixed resistor pack anyway, if i want to do more electronics in the future
You can buy from RS, Farnell and Rapidonline as well !

yeah but for a few parts i don't really wanna pay handling and shipping fees

Its still cheaper than Maplin, and the choice is a lot wider.The kids in the electronics club I help run club together and buy a lot at one time from Rapid

ok. I don't need much more now anyway that's the thing i'd rather avoid it if i can. I'll compare some prices.

BTW i need to find a 10kΩ 1/2 watt potentiometer. I believe a linear type. I found a couple of miniture ones and even standard ones but none that appearred to be 1/2W rated.

But i'll see what rapid electronics has on that subject too
