Most people choose 2 hours as that is generally when the glucose released from what you eat will be at a peak. So after 1 hour it will still be on the rise unless you have only eaten something which is quickly converted and longer than 2 hours it will be on the decline unless you have eaten something really slow to metabolise or including high fat as that slows the conversion.
On average 2 hours would be good for most people with most meals.

As @Leadinglights says, you are looking for the time when the glucose is at a peak.
Different foods peak at different times - those of us treating their diabetes with insulin will know about fast acting carbs which will peak in 10 to 15 minutes. We also know about slow acting melas such as pizza which can be affecting our levels 4 or 5 hours later.
Managing diabetes is about managing a lot of approximations - approximate carb content, approximate blood sugars, approximate timings, ... therefore, we need to make assumptions.
One of these assumptions is that most food will on average peak at around 2 hours.

I think the ‘peak time’ can vary from meal to meal, and from person to person?
We have guidance of levels to aim for at 2 hours after eating:
4-7 pre meals and
less than 8.5 by 2 hours after meals
If your ‘first phase’ insulin response is impaired, you may find 1hr would be higher, and then when the second phase has begun to work through, it may be lower at 2 hours.
So I guess it really depends on whether you are looking for a fixed target at 2hrs, or to aim to reduce the maximum peak that the meal ever reaches?
Both methods are fine, it‘s just what feels right to you 🙂
