How many photos do you need for a 26, 50 or 78-page photo book?

The question comes up before every album: how many photos does the book need, and how many should be uploaded to get there. The two numbers are different, and confusing them is the most common reason a first photo book disappoints. This article gives the ratio MakeAlbum works to, what it means for the three page counts people choose most, and where the count moves.

The ratio: about 2.2 photos per interior page

MakeAlbum's layout engine builds each spread from a library of templates for the square page: a single full-bleed photo, a pair, a small grid, a photo with a caption, and the text pages that open the book and each chapter. Averaged across those templates, a book comes out at roughly 2.2 photos per interior page, after allowing for the title page and the chapter openers.

The curation uses that ratio to decide how many frames to select. It picks for the page count you have chosen, with a floor of 60 photos for the smallest book and a ceiling of 280 for the largest. So:

• 26 pages (13 spreads): about 60 photos selected. €179.
• 50 pages (25 spreads): about 105 photos selected. €225.
• 78 pages (39 spreads): about 170 photos selected. €279.
• 130 pages (65 spreads): about 280 photos selected. €379.

Price is linear between those points, about €1.92 per extra page, and includes standard tracked shipping. The pricing page lists every step. If you change the page count in the editor after curation, the selection is topped up or trimmed to match, and the price updates as you go.

How many to upload

More than the selection, and usually a lot more. The pre-filter and the curation work by choosing, so they need something to choose from. Between 50 and 300 photos per album works best, and curation needs at least 30 to start.

A rough guide, based on how a camera roll shrinks through the pipeline:

• Screenshots, documents and frames with obvious blur or exposure problems are set aside first. On a typical phone roll that is a tenth to a quarter of the set.
• Near-duplicates and bursts collapse to one frame per moment. On a holiday roll this often halves what remains; on a family day out, more.
• From the moments that remain, the curation picks the strongest to fill the page count.

Working backwards, a 26-page book is comfortable from 100 to 200 uploaded photos, a 50-page book from 150 to 250, and an 80-page book from 200 to 300. Below those ranges the book still gets made, but the curation has fewer moments to choose between and more of what you uploaded ends up in print. Above them, the selection gets pickier and the book gets better, up to the 500-photo limit per album.

If you have fewer than 60 usable photos, stay at 26 pages. A short book with room around each frame reads better than a longer one padded with the frames the filter set aside. The holiday photos article makes the case for 26 to 40 pages for most trips.

Why fewer is better

It is tempting to treat the page count as a measure of how much of the trip or the year made it in. In practice the books that get opened are the ones that can be read in one sitting.

The layout engine gives its best treatment, a single frame across a full page or a full spread, to the strongest photos in each chapter. Every extra page has to be filled with something, and the further down the ranking the engine goes, the more the book fills with near-misses and second-best frames that dilute the good ones. A book of 60 well-chosen photos looks like a book. A book of 280 from the same weekend looks like a camera roll with a cover.

There is also the object. A 300 × 300 mm layflat book has thick, board-mounted pages, and a 130-page one is heavy in the hand. That size suits a wedding with several hundred guest photos or a whole year of a family, which is what the family year-in-review page is about. For a fortnight away, it is more book than the material can carry.

Chapters change the count

Each chapter costs pages before its photos do. A chapter opens with its hero frame full-bleed and its title on the facing page, which is one spread. A 26-page book has 13 spreads; with a title page and three chapters, four of those spreads are structure and nine hold the body of the book.

That is the reason to keep chapter counts proportionate. As a rule of thumb: three or four chapters for 26 pages, four to six for 50, and six to eight for 78. The curation aims for three to eight chapters by default, and in the editor you can ask for fewer or more, a single chapter, or chapters by day, place or people. Merging two thin chapters returns a spread to photographs.

Chapters also change which photos are worth having. One wide establishing frame per place, the one that says where you were, is worth more than ten close-ups of the same view, because it is the frame the engine will choose to open the chapter. If a chapter has no such frame, the opener falls to a portrait or a detail, which works but carries less.

Bursts count as one

Ten frames of the same jump are one photo, not ten. The pre-filter treats frames whose perceptual hashes sit within a small distance as one moment, and frames shot within three seconds of each other as a burst even when a reframe pushes the hashes apart. One frame is kept from each group, scored on the recognition service's quality estimate, sharpness, resolution and the number of faces; the rest stay in the tray, where you can swap a sibling in if the chosen one has the wrong expression.

So when you count your photos, count moments. A roll of 400 frames that is really 120 moments will fill a 26-page book well and a 50-page book thinly. This is also why hand-pruning bursts before upload does not help the count: the ratio is applied after the grouping, not before.

A worked example

A ten-day trip with two phones: 1,100 frames after both are exported. The filter sets aside about 150 screenshots, maps and blurred frames, and the burst and duplicate grouping brings the rest down to around 300 moments. That is a comfortable source for a 50-page book of about 105 photos in five chapters, one per place, at €225. It would also make a 26-page book of 60 in three chapters, at €179, which for many people is the one that gets read.

What to do with the number

Decide the page count first, upload everything, and let the curation select. Then read the chapter review with the ratio in mind: if a chapter looks thin, move a few photos into it or merge it with its neighbour; if the whole book feels short, add a spread where it needs one rather than jumping a size. Every spread can be edited before you approve, and the examples show what 26 pages looks like with real frames from one afternoon.
