## Families in Hemel and the market towns

Dacorum in census table TS007A (2021), via Nomis, six bands next to England.

| Age band | Dacorum residents | Dacorum share | England share |
| --- | --- | --- | --- |
| Under 5 | 9,581 | 6.2% | 5.4% |
| 5 to 9 | 9,929 | 6.4% | 5.9% |
| 20 to 24 | 7,104 | 4.6% | 6.0% |
| 35 to 39 | 11,101 | 7.2% | 6.7% |
| 40 to 44 | 11,030 | 7.1% | 6.3% |
| 85 and over | 4,011 | 2.6% | 2.4% |

Young children and their parents are above the national share, and people in their early twenties well below it. Beyond Hemel Hempstead, the ONS lists Berkhamsted at 21,240, Tring at 11,960 and Bovingdon at 5,310, all inside Dacorum. The national curriculum for England applies in local schools, and our timetable leaves out whichever holiday weeks you tell us about.

The Hemel Hempstead project

## Folding 26 sheets of 1855 paper

Only one shape survives halving unchanged.

The learner types Herring's 26 fine paper sizes into Python, converting fractions like 13½ into decimals, and works out each aspect ratio, the long side divided by the short. Then comes the folding function: halve the long side and swap if needed. For Foolscap, 17 by 13½ inches, the ratio starts at 1.259; fold it and it jumps to 1.588; fold again and it returns to 1.259. The sheet keeps flipping between two different shapes, so a folded Foolscap page never looks like a small Foolscap.

| Sheet | Size in inches | Ratio | After one fold |
| --- | --- | --- | --- |
| Super Royal | 27 by 19 | 1.421 | 1.407 |
| Imperial | 30 by 22 | 1.364 | 1.467 |
| Demy | 20 by 15½ | 1.290 | 1.550 |
| Foolscap | 17 by 13½ | 1.259 | 1.588 |
| Pot | 15 by 12½ | 1.200 | 1.667 |
| Sheet-and-half Foolscap | 24½ by 13¼ | 1.849 | 1.082 |

Algebra explains it. If a sheet has ratio r, folding it gives ratio 2 divided by r. The shape stays the same only when r equals 2 divided by r, which means r is the square root of 2, about 1.4142. Of Herring's 26 sizes, only Super Royal comes within 2 per cent of it. The learner then builds the modern answer: a sheet of exactly one square metre with sides in the ratio root 2 measures 1,189 by 841 millimetres, and halving it four times gives 297 by 210 millimetres, the familiar A4 page.

The final step is data checking. Herring lists "Double" versions of some sizes, and the program tests whether each is really two of the original laid side by side. Double Foolscap, 27 by 17, is exactly two Foolscaps. Double Post is within 2 per cent. But Double Pot has four times the area of Pot, and Double Elephant only 1.66 times Elephant: the names are traditions, not rules. The learner writes tests for the fold function, including that a root-2 sheet returns its own ratio.

### Ages 8 to 11

Fold A4 and a square of paper in half several times and measure the shapes with a ruler.

### Ages 11 to 15

Write the ratio and fold functions in Python and test all 26 sizes.

### Ages 15 and up

Prove the root 2 result, build the A series, and check the named double sizes.

### Old books, our code

The Two Waters quotation is from Alexander Watt's The Art of Paper-Making, and the sizes from Richard Herring's Paper & paper making, both on Project Gutenberg. The ratios, folds and checks are ours.

Why Two Waters

## Continuous paper and the Fourdrinier machine

What the two Victorian books say.

| Detail | What the book says |
| --- | --- |
| The machine | Named after the Fourdriniers, who improved an earlier French design |
| The engineer | Built with the help of Bryan Donkin, according to Watt |
| First working model | 1803, erected at Frogmore, Hertfordshire |
| Second machine | 1804, at Two-Waters, Herts, completely successful |
| Smallest fine size in Herring | Pot, 12½ by 15 inches |
| Largest fine size in Herring | Antiquarian, 53 by 31 inches |

Aspect ratios matter far beyond paper. Screens, photographs, video frames and printed posters all have them, and code that resizes an image without keeping the ratio stretches every face in it. Web designers, game developers and anyone building a printing tool meet the same rule the learner found by folding Foolscap: scale both sides together, or the shape changes. Hertfordshire has more than one place called Frogmore, so the page says only what the books say about where the first model stood.

Modern Age Coders has no connection with Project Gutenberg or the ONS. Their books and figures belong to them; this program and whatever it gets wrong belong to us.

Learning stages

## From folding paper to image processing

Years are a guide; the trial lesson decides the level.

Years 1 to 4

### Shapes in blocks

Block coding with shapes, scaling and simple games.

[Coding for Kids](/courses/kids-coding-blocks-masterclass)[Scratch Coding for Kids](/courses/scratch-programming-complete-course)Years 5 to 8

### Python and ratios

Functions, fractions and ratios in Python.

[Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Years 9 to 13

### Proof and AI

Algebra in code, data and AI alongside GCSE and A level.

### Useful programming

Adult Python with data and graphics.

[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Data Analysis Course](/courses/data-analysis-mastery-course-college)AI and images

## Does an AI keep the shape when it resizes?

Stretching is the most common image bug.

Ask a chatbot to write code that resizes a picture and it may set the width and height separately. The code runs, and every face in the picture comes out slightly stretched.

A Hemel Hempstead learner who has folded Foolscap in Python knows to check that the ratio survives any change of size.

Making sure a picture keeps its proportions through the code is the kind of care that makes programming worth learning in Hemel Hempstead in 2026. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026).

Lesson set-up

## Hemel, Berkhamsted and Tring, all online

Anywhere in Dacorum joins by live video.

### The student codes

Every program is typed by the learner; the tutor follows on the shared screen and guides with questions.

### Starting at the right rung

From Year 4 up to Year 12, placement follows the school year and what the trial reveals, with the correct exam board in mind.

### A trial on the house

You pay nothing for the first lesson, and you leave it with a plain answer about what fits.

### Peers at your stage

Each class gathers five to ten UK learners who have reached the same point.

### Term-time rhythm

Two lessons weekly in term; none in the holidays.

### Steady lesson time

Our teachers adjust for UK clock changes, so your slot does not move.

Why the groups are online

Five Hemel learners at one level and one free hour rarely live near each other. Online groups give everyone the right class.

FAQ

## Hemel Hempstead questions

The town, the paper project and how lessons work.

### What is the population of Hemel Hempstead?

Of course. Whether you live in Apsley, Berkhamsted, Tring or Bovingdon, anyone aged 6 to 67 can study coding, AI, Python and maths with us live online.

### What is the paper size project?

Learners test 26 paper sizes from Richard Herring's 1855 book in Python and discover why only a root 2 shape survives folding.

### Why is A4 the shape it is?

Its sides are in the ratio of the square root of 2, so folding it in half gives the same shape at half the size.
