A plain guide for homeschool parents to add up the week's class video time, with steps, the tools to try and the mistakes to avoid.

List each class's videos with their lengths, add the lengths per class and per day, and compare each day's total with the time set aside for it.

| Option | What it does for the week estimate |
|---|---|
| Paper and a calculator | You add up each class's video lengths by hand |
| Spreadsheet | A length column and a sum at the bottom gives the week's total |
| YTSort | Shows total, average, shortest and longest video duration for the playlist [^1] |

## What you need before you start

Estimating the week's class watch time takes only a few things.

- **A list of the week's classes.** Note which subjects and lessons are scheduled, and on which days.
- **The length of each video.** YouTube shows it on each thumbnail, and the video page shows it too. You need it to add up.
- **A rough screen-time budget per class.** Decide how much time each subject may take, so you have something to compare the total against.
- **A place to keep the totals.** A notebook, a spreadsheet line or the playlist itself all work. What matters is that the numbers live in one place.
- **A web browser.** Only needed if you want a tool to add the lengths for you. Set the tool up once, before you start, following its own instructions.
- **A decision about repeats.** Some videos are watched more than once. Decide whether to count each viewing or each video once.

Set aside a few minutes before the week begins. Total up the videos once, then adjust as the week goes on.

## Step by step

These steps work with any tool, including a pen and a sheet of paper.

1. **Open the week's classes.** List every class scheduled for the week, by day.
2. **List every video with its length.** For each class, write the title and the time shown on the thumbnail. Do not add yet.
3. **Separate required from optional videos.** Some videos are core lessons and others are extra. Keep the totals for each, because they are handled differently.
4. **Count repeats.** If a video is watched more than once, decide how it is counted and keep that rule the same for every class.
5. **Add the lengths per class.** Total each class's videos. This is the class time for the week.
6. **Add the classes per day.** Group the daily totals to see how much time each day needs.
7. **Compare with the time set aside.** Put each day's total next to the block of time you planned. This shows where the week overruns.
8. **Adjust the schedule.** Move optional videos to a lighter day, or drop them.
9. **Apply the totals.** Write the final daily totals where the family can see them.
10. **Review after the first few days.** If a class runs longer or shorter than planned, update the estimate.

## Tools that can do it

You do not need software for this. Here are options to consider.

**Paper and a calculator.** You write each title and length and add them up by hand. Nothing is published here about price or limits, and the page does not state why.

**A spreadsheet.** A column for the class, a column for the length and a sum at the bottom gives you the week's total. Check how it behaves on your phone if you plan to use it away from your desk. Facts about specific spreadsheet apps are not provided here, so check their own pages for limits and cost.

**YTSort.** YTSort is one option. It shows total, average, shortest and longest video duration for the playlist. [^1] That total is the watch time for the videos in the playlist, which is the basis for a week's estimate.

You can get YTSort through a bookmark, a browser script, or a Chrome Web Store extension. [^1] The extension needs Chrome or Edge, and the script version works in any browser, including Firefox, with Tampermonkey, Violentmonkey or Greasemonkey installed. [^1]

## Common mistakes to avoid

**Counting every video once when some are watched twice.** Decide the rule first and apply it to every class, or the week's total comes out short.

**Forgetting optional videos.** They still take screen time. Total them separately and decide whether they fit before leaving them out.

**Trusting a total without a look.** Add the lengths once, then add them again. A quick check catches a misread thumbnail.

**Underestimating a long video.** A lesson that runs over its estimate eats into the next class. Leave a little room each day.

**Estimating the whole week from one video.** Different classes have different lengths. Total each class instead of applying a single average.

**Never reviewing the estimate.** If a class runs long, update the week's total rather than keeping the old number.

## Frequently asked questions

### Can YTSort help estimate a homeschool week's class watch time?

Yes, for the videos in a playlist you own. YTSort shows total, average, shortest and longest video duration for the playlist. [^1] That total is the watch time for the videos already in the playlist, which is the starting point for a week's estimate. Check how videos outside the playlist are handled, and give a class with videos elsewhere its own total.

### Which browsers work with YTSort?

The add-on needs Chrome or Edge. [^1] The script works in any browser, including Firefox, once you add a script manager such as Tampermonkey, Violentmonkey or Greasemonkey, a small add-on that runs scripts for you. [^1] YTSort can also be run from a bookmark. [^1]

### Can the new playlist order be checked before it is applied?

With YTSort, yes. [^1] It shows the before and after order so you can check it before applying. [^1] With a paper list or a spreadsheet, you see the order as you write it, so read it through once before you start watching.

### Can YTSort sort only videos within a length range and move the rest to the end?

Yes, YTSort can sort only videos within a length range and move the rest to the end. [^1] For a homeschool week, that helps keep a class's shorter videos together while longer lessons move down the list.

### How is a week's class watch time totaled by hand?

List each class's videos with their lengths, add them per class, then group the class totals by day. Compare each day's total with the screen time set aside for it. If a class overruns, update the total. Review the estimate after the first few days and adjust.

YTSort is free; all install options include the same features. [^1] - [Visit YTSort](/go/start-ytsort)
