Sixteen ana

System note. Keep the ana out of the museum.

Contents

I never spent an ana. I heard it: from family, from books, from songs and poems.[1] As a child I held 25-poisha and 50-poisha coins and called them char ana and ath ana, four ana and eight.[2] The decimal law was older than me. The sixteenth was still in my mouth.

My stylesheet counts in ana. Sixteen ana make one taka, and sholo ana, sixteen ana, means whole: wholly genuine, wholly mine.[3]

I like that line. I also distrust it. A label like heritage, legacy or archive can sell a cultural product. I may be doing the same to a money unit my country stopped using before I was born. So I checked, and then I changed the code.

The ana is a share of a whole, never a size. Sixteen is the ceiling.

Origins

The sixteenth is older than the coin. Before the Mughals, the ana was a unit of count, not metal in the hand. In one Bengal shell table, four kori make a gonda, twenty gonda a pon, four pon an ana, four ana a kahon and four kahon a taka. Sixteen ana to the whole, counted in shells.[4]

Bengal halved its silver too. Sultanate taka coins came in three weights, about 160, 80 and 40 grains, with half and quarter pieces beside the whole. A half, then a quarter.

The rigid anna ladder is colonial. The East India Company’s Coinage Act of 1835 fixed a uniform rupee across British India, and with it a strict copper hierarchy: “Rupee = 16 annas = 64 pice = 192 pies.” India went decimal in 1957. Pakistan, East Bengal included, followed in 1961. The taka of 1972 was born in 100 poisha and never had an ana. Through all of it, Bengalis never stopped calling the rupee taka.

Still in use

The ana is dead as money. As a share, it still works.

Land
In November 2025 the High Court of Bangladesh decided a revision over a “4-anna share” of inherited land. A month later another judgment wrote shares in decimals. Both languages sit in current law.
Gold
Jewelers price gold per bhori, 11.664 grams, and a bhori is sixteen ana. In February 2026 the president of the jewelers’ association told BBC Bangla that the trade now calculates in grams. Older buyers still think in bhori and ana. I hear bhora, full, inside bhori.[5]
Speech
Sholo ana means wholly. The proverb says a man takes sholo ana for himself when it is his turn: the whole share, when the share is his.[6] Sukumar Ray’s poem on a life’s accounts ends on a refrain: all sixteen ana of a life wasted. The sum turns on the one counting.[7]
Script
Bengali writing has its own signs for sixteenths, with named points: siki for four ana, adhuli for eight, poune for twelve.[8]

Cinema and song

The coins left the pocket in 1961. The ladder stayed in film and song, as a ledger of class, sufficiency and loss.[9]

Taka Ana Pai (1970)
Babul Chowdhury’s film, written by Zahir Raihan on the eve of 1971, takes its name from the descending scale. Taka, ana, pai: class as denominations, with the poor at the bottom of the ladder.
“Kokhono Shomoy Ashe” (1992)
Kabir Suman borrows the old idiom for a windfall, fourteen found ana. The singer waits for the last two, while a familiar adhuli slips away unnoticed. Joy arrives by accident. Loss leaks from below.
“Porashonay Jolanjoli” (1995)
Moheener Ghoraguli lose four ana and call the twelve that remain more than they wanted. Sholo ana, the full ledger of school, career and approval, is the trap. The missing quarter is where freedom lives.
“Aat Anar Jibon”
In Monir Khan’s song a life starts at eight ana, half a taka. Sleep takes four, love’s deceits two, and two remain. The whole was never offered.

One song subtracts by choice, one by leak, one never had the whole. In each, the missing ana is where the feeling sits. The songs count shares, never sizes. So does the land.

The charge

At the browser’s default text size, 16 pixels, one sixteenth of the text is exactly one CSS pixel. My ana is the web’s pixel with a Bangla name.

That 16 pixels has a history. In 1998 Todd Fahrner traced it on the W3C style list to an old default of 12 points, drawn at 96 pixels per inch on Windows. The imperial inch, the printer’s point, a Microsoft screen: my “whole” rests on that chain.

Design scholars name this risk. In a 2018 roundtable on decolonizing design, Matthew Kiem warned that designers are “adept at mimicking the representational dimension of movements.” Laurajane Smith argues that heritage is made by present authority for present uses, and naming a unit ana is such an act. Tuck and Yang wrote that decolonization is not a metaphor, and named “moves to innocence” that ease guilt and change nothing. Their subject is settler colonialism and land, so I hold the argument with care. A renamed unit returns nothing to anyone.

One more fact is mine. Part of the name was written for an outside reader: a supervisor, a panel. A Bangla reader does not read stylesheet comments. That leans toward display.

From name to share

Until November the grid counted sizes in ana: 14 for a label, 24 for a line. A size can run past sixteen, and a whole that can be exceeded is no whole. The land never works that way. A four-ana share is a quarter of this holding, whatever its size.

So the rule changed. Each share names its whole first, and nothing exceeds sixteen. Two wholes in the stylesheet now work as shares.

WholeShareBeforeAfter
The Bangla line box12 ana ink, 4 ana clearance1.5 + 4 ÷ 16 = 1.75, a Latin line plus an add-on1.25 × 16 ÷ 12 = 1.67
The paper12 ana text, 4 ana margin38 spaces, chosen by eye29 × 16 ÷ 12 = 38.67 spaces

Table 1. Two wholes, before and after stylesheet 7.5.

The 1.25 is measured, not borrowed. In the Bangla font, the tallest stack reaches 1,950 units above the baseline and the deepest descender 618 below, out of 2,048: 2,568 ÷ 2,048 = 1.25 of the text size. The Bangla line now starts from Bangla ink. Before, it started from the English line and asked for extra. The paper starts from the reading text, so every line breaks as before and the margin takes the remainder.

Two ideas failed the same test and were dropped. A rule of fourteen ana content and two ana reader slack described something already true: the page passes the reader-spacing test, and naming it changed no number. A page budget counted in ana, sixteen ana to 128 kilobytes, relabeled kilobytes. No one reckons downloads in ana.

A share earns its name only when it changes a number. Otherwise it is a costume.

The speed decision that followed is not an ana decision, and I keep it apart. In stylesheet 7.6 the English font is fixed at its reading size, 36 kilobytes instead of 80. The home page fell from 91 to 47 kilobytes, the working paper from 226 to 182. The spirit is twelve ana, enough. The arithmetic is plain kilobytes.

Proportion

Decimal money standardized our coins. Global software standardized our screens, and with them the 12-column grid and the golden ratio as defaults.

The ana unsettles both, quietly. One anna held 12 pai, so twelve was always inside the sixteen. The 12-column grid and the 16-ana grid are cousins.

The golden ratio, about 1.618, splits a line at 61.8 and 38.2 percent. Ten ana and six ana split it at 62.5 and 37.5, a ratio of 1.667. That is 5:3, a Fibonacci pair, so the ana approximates the golden ratio. It does not replace it. Its claim is smaller and honest: whole numbers, at every size. The golden ratio’s own aesthetic authority is weaker than its reputation.[10]

The ana also halves, as Bengal’s silver halved and the machine counts in twos. One sixteenth adds cleanly in binary. The fit is a meeting of two halving systems.

Beyond the stylesheet

A unit is a way of thinking about shares. Three practices follow from the songs and the proverb.

Twelve ana
Design for enough. Much of product design maximizes attention and output. A twelve-ana product delivers three quarters of a use and leaves four ana open for rest, chance and life offline.
The missing two ana
Design for the gap. A hospital flow, a bus route or a payment service is measured by speed and throughput. The ana asks for the unaccounted fraction: a patient’s fear, a vendor’s informal ledger, a day worker’s lost adhuli. A service that demands sholo ana from tired people has the arithmetic backward.
Sixteen tokens
Make power countable. In a co-design session, give the table sixteen tokens to place across stakeholders. If a donor holds fourteen ana of the decisions and the community two, the proverb becomes a measurement, and eight to eight becomes a goal.

The same test holds here. If twelve ana is only a poetic name for 75 percent, the ana stays in the museum and I have decorated the glass case. The practice counts only when the share logic changes a decision.

What remains

Limits
One Bangla font measured, by its outline data, not by readers. One reader’s eye, mine, judged 1.67 against 1.75. No Bangla reader has tested the page yet. The web’s 16-pixel base still sits under everything. The English line, 1.5, still comes from Latin habit.
Possible
Derive the English line from the same whole. Try a sixteen-part layout grid, and spacing measured as shares of each container. Run the sixteen tokens in a real workshop.
Next
Test the Bangla line with Bangla readers. Publish the grid as a small open stylesheet, sholo-ana.css, with its tests. Record what changes and what does not.

Verdict

Partly performance. The name alone performs. The use carries something real.

The ana is a share of a whole. My unit is relative to the text it sits in, so when a reader raises the text size, every ana grows with it. A pixel stays put. That is how the land ana works too. It is alive, in a court, a gold price, a song.

So I claim less. The grid is a vernacular layer on a Western technical base. It locates me. It marks the pixel as one local system among others. Since 7.5 it also changes two numbers that a pixel grid would not. It does not decolonize anything, and I will not say it does.[11]

Endnotes

The endnotes hold the Bangla, the doubt and the seam.

  1. বাস্তবে বা দৈনিক হিসাবে আনা ব্যবহার করিনি। আনা শুনেছি পরিবার থেকে, বই থেকে, গান থেকে, কবিতা থেকে। The ana reached me as sound before arithmetic. That order matters for this essay: I learned the whole as a feeling before I learned it as a fraction.

  2. পঁচিশ পয়সা আর পঞ্চাশ পয়সার কয়েনকে বলতাম চার আনা, আট আনা। Decimal coins, sixteenth names. A child in the 1990s, decades after decimalization, still paid in shares of sixteen.

  3. ষোল আনা: পুরোপুরি, সম্পূর্ণ। যেমন, ষোল আনা খাঁটি, wholly genuine; পড়াশোনা না জানলে জীবনটা ষোল আনাই বৃথা, without learning, a whole life wasted. The idiom measures completeness, never size.

  4. কড়ি, গণ্ডা, পণ, কাহন। The table follows one Banglapedia version. Other tables differ: in land measure, twenty gonda make a kani, not a pon. The shells were counted long after the coins changed.

  5. ভরি, ভরা। I hear the full in the unit, and I have not found an etymology that confirms it. The weight itself moved: 11.664 grams is the tola as the colonial state fixed it in the 1830s, heavier than the Sultanate silver taka. Even the gold whole was redefined by law.

  6. নিজের বেলায় ষোল আনা। The proverb names an unequal share. It is a critique built into the unit: the whole is fair only when it is counted for everyone.

  7. সুকুমার রায়, “জীবনের হিসাব”, আবোল তাবোল (১৯২৩)। The refrain: ষোল আনাই মিছে, all sixteen ana in vain. A babu mocks a boatman’s ignorance, ana by ana, until the boat sinks and the babu cannot swim.

  8. সিকি (চার আনা), আধুলি (আট আনা), পৌনে (বারো আনা)। Poune also means “a quarter short of”: পৌনে পাঁচটা, a quarter to five. The share names the gap.

  9. টাকা আনা পাই (১৯৭০), directed by Babul Chowdhury, screenplay by Zahir Raihan. মহীনের ঘোড়াগুলি, “পড়াশোনায় জলাঞ্জলি”, lyrics and music by Gautam Chattopadhyay and Tapas Das (Bapi), on আবার বছর কুড়ি পরে (1995). কবীর সুমন, “কখনো সময় আসে”, on তোমাকে চাই (1992); its পড়ে পাওয়া চোদ্দ আনা is an older idiom for a windfall. মনির খান, “আট আনার জীবন”. The arithmetic is retold from my memory of the songs. One is a Kolkata city song, one a song of Bangladesh’s small towns. Both count a life in ana.

  10. The name golden ratio is modern; Euclid called it extreme and mean ratio. On the claims made for its beauty, see Markowsky (1992).

  11. A seam, as the writing style guide defines it. The memories, songs, history paragraphs and the three practices are mine. The research, the font measurement and the blending were done with a generative language model. Song details come from my memory and the credits I supplied.
