A personalized book fails quietly. The child opens it, looks for herself, and does not find herself — and nothing on the page is wrong enough to point at. The drawing is good. The name is spelled right. That child is simply not her.
We make these books, so we are not a neutral party and you should read this knowing it. What we can offer is the list we go through ourselves before we let a book out. It is short, it is mostly not about the art, and it works on somebody else’s samples exactly as well as on ours.
The checks
How to choose a personalized book from the sample pages alone
The margin says what kind of claim each check rests on: something we watched, something we measured, or a mistake of our own. We would rather label them than let four things of different weight sound equally certain.

What we saw
1. The cover does not count
A cover is not made the way the inside pages are made. In our own system it is separate machinery: its own camera distance, its own framing rules, its own overrides — and one path that produces a cover with no book behind it at all, because a cover on its own is a marketing image. We wrote that path. It is why we know how little a cover proves.
A cover shows the best single page somebody can produce, made under rules the rest of the book never sees. If covers are all there is to look at, that is itself an answer.
Check it yourself Ask to see two pages from the middle of the book. Not page one.
Nine covers off our own shelf. Every one of them is the strongest frame in its book, produced by machinery the interior pages never touch — and we know that because we wrote that machinery. Put next to each other they look like a catalogue, which is the point: this is exactly the material a shop shows you, and it is the material this check tells you to skip. -
Something you can measure
2. Measure the face, not the drawing
The most useful check is also the least obvious, because it asks you to ignore the thing your eye goes to. Do not judge the illustration. Measure how much of the page height the child’s face takes up.
There is a floor under which no amount of skill helps: eyes, mouth, the line of a jaw, the way hair sits — none of that survives in a few millimetres. On our own books we work to about one eighth of the page height. Under it a page can still be lovely, and the face is nobody in particular.
Check it yourself Put a thumb over the child’s face on an inside page and walk it up the page. If the face fits 8 times into the height, look at that page hard before you buy.

Our mistake, mended
3. Go and find the crowd scenes on purpose
Crowd scenes are where faces shrink, and not because anyone stopped caring. When a picture has to hold more people, the cheapest way to fit them in is to move the camera back.
We did this to ourselves on a birthday book. We asked for the party guests to actually be in the picture with the birthday child, and the renderer obliged by stepping backwards: we gained a whole porch, a yard, an apple tree and the neighbours’ houses, and the child’s face fell from about an eighth of the frame height to about a thirteenth. The same book went from seven usable pages to two.
The rule we wrote afterwards is that a crowd enters by cropping the world, never by retreating from it — guests as half figures at the frame edge, an arm reaching in from off-screen, a face leaning in at the corner. Crowded should mean the frame is full of people, not far from them.
Check it yourself Find the busiest sample page — the party, the classroom, the group of friends — and measure that face. If it has gone there, it has gone in the book.

Our mistake, mended
4. Count the pages where the child faces you
A face turned toward the reader is the only place recognition can happen. Seen from behind, in silhouette, or in distant profile, any child fits.
We learned it in the least dignified way available. A cover plan describing the hero gazing up at a tower came back with the child painted from behind — on the cover, of a book whose entire point is a face. Our rule now says the face is turned toward the reader and clearly visible, three-quarter or near front, never a back of a head, and it overrides the plan even when the plan says look up or away. We wrote that rule for the cover, where it is non-negotiable — which is exactly why the counting belongs on the inside pages.
Check it yourself Count the sample pages showing the child’s face from the front. One — usually the first — is not enough to carry a book.
Two whole books, every page labelled, nothing cropped away — so the count is a thing you can perform rather than a number we assert. Open it full size and go along the strips: how many of those twenty-eight pages actually turn the child’s face toward you? Do this to us before you do it to anyone else. A shop that will not show you the pages this way has told you something.
Before you buy
One more question: personalized how?
Ask it in those words. Is it the name only? The name plus a set of preset choices — hair, skin tone? Or that particular child’s face, worked from a photograph? All three are sold as personalized, and they are not the same product at all.
Presets deserve the hard look, because they can be hollow without anybody lying to you. Ours were. We offered eight skin tones, and the words printed under the swatches — ivory, porcelain, cream, golden, honey, almond — were the same words we handed to the illustrator. Six of the eight came back as approximately the same child. Those names are not a ladder to a picture-making model; almond in English is mostly a word about eyes. Only the two darkest read unambiguously as dark, so the range had six near-identical steps and then a cliff. We fixed it by sending plain depth words instead of the ones we show people.
That one carries to any book: the words a customer picks from are chosen to sell, and they are not necessarily the words the picture is made from.
Evidence
What our own numbers are worth
-
Still not fixed
Our own sample books do not all pass check 2. The instruction that paints some of them still says the hero is at roughly 15% of the frame while the painted environment carries the storytelling — and a child painted that small has a face far under an eighth of the page height. One of our rules sizes the whole child, the other measures only the face, and the face is the one that loses. We have not changed it. In a sweep of fifty-four books — six story themes across nine languages — the ones that fell under our own floor most often were the big-landscape themes, adventure and fantasy. Bedtime and friendship never did.
About the ruler itself
The tool we measure faces with reports the clearest face on the page, which on a page with six children at a party is not always the birthday child’s. We built three conclusions on that number before checking what it actually returns, and all three had to be withdrawn. Identify the face with your own eyes first, then measure that one.
And treat an eighth as a place to look rather than a verdict. The number started life as a crop we needed for vertical video, not as anything about reading; when we went back to the two lowest-scoring pages in one book, both were good pages.
Using these
They have to work on our books too
A check our own books pass by definition is not a check. It is an advertisement holding a ruler. Check 1 disqualifies our own cover path, check 2 fails some of our own sample pages, and checks 3 and 4 are mistakes we made and had to write rules against. Run all four on our own sample pages before you believe any of it — check 2 is where we would start, and it is the one we most often fail.
People who judge illustration for a living ask a version of check 4 too. The criteria for the Carnegie Medal for Illustration include one line that a parent holding four sample images is asking as well: Are characters and settings consistently portrayed?
The child on page nine has to be the child on page two.
