There are a whole lot of plans available on the net. Don't be put off by imperial vs metric. You can readily get a tape & rule with both, or just convert - its not hard. And in any case, you should not blindly cut all components from a "cut list" but build & fit the key components as you go.
Importantly, you need to decide on the use for your bench. If you plan on hand tool work, it will need to be very sturdy & have other key criteria. A bench for primarily power tool use can get away with lighter construction. Do you plan to move it often? Will it be taken away for on-site work? What other key constraints are there? And I assume (as you have posted to a woodwork forum) that the bench will be for woodwork. A metal workers bench will have different construction & needs.
Here are some resources:
This is a great article with construction explanation from Popular Woodworking for a good, inexpensive bench . Substitute any timber you like. I prefer Oregon (Douglas Fir) if you can get recycled timber at a good price, as its easy to work & the old stuff is generally stable, quite dense & close grained. However any well dried timber will work OK.
