About
Who and how
Who makes it, where the numbers come from, how the sightlines are worked out, and where to write when something is wrong.
This site answers the questions you ask yourself with a ticket in your hand: what the view is like from my seat, how to get there, and what they let you take in. That is all.
What this is
An independent supporters’ site about Bulgarska Armia Stadium. It is made by someone who goes to the ground — not by the club and not by the operator.
The official stadium site shows what the building looks like. This one shows how it is used. The two do not get in each other’s way.
What it is not
- It is not official and has no connection to PFC CSKA, to the owner or operator of the stadium, or to any ticketing platform.
- It uses no club marks, crests, official renderings or press photographs. The drawings and diagrams here are made by us.
- It does not sell tickets and does not link to sales.
- No ads, no tracking, no mailing list and no sign-up. Email is for photographs and corrections. Fonts are served from here.
- Videos are watched on YouTube through youtube-nocookie.com and are never re-hosted.
What is known about the stadium
Gathered from public sources and checked on 2026-08-25. Nothing here is our own claim — every line says where it came from. Where sources disagree, the disagreement stays in.
Where the data comes from
Every source is named. If something here has no source, it is a guess, and it has to say so.

How we work out the sightlines
Nothing at this stadium was measured by us. The sightline numbers come out of a geometric model of the stand, and the model is fed by five numbers per sector: distance from the pitch to the first row, height of the first row above the pitch, row depth, rise per row, and number of rows.
Those five numbers for all 4 sectors sit in one file — src/data/geometry.json — and every number on the site is computed from them. Nothing is typed in a second time.
C-value
The main number. It says by how much your line of sight clears the head of the person in front of you, while you are looking at the nearest point of the pitch you need — the touchline for the side sectors, the goal line for the sectors behind the goals.
- D
- horizontal distance from the eyes of the person in front of you to the point on the pitch
- N
- height of their eyes above pitch level
- R
- rise of one row
- T
- depth of one row
The result is in metres and we show it in millimetres. Nothing is worked out for the first row — there is nobody in front of you there, and it says so.
The bands
These are rough guides from design practice, not a standard. Nobody is obliged to meet them and nobody certifies against them.
- 120 mm and up Excellent You see the pitch without thinking about the head in front of you.
- 90 – 120 mm Good An ordinary stand. Nothing gets in your way.
- 60 – 90 mm Acceptable You notice the person in front, but you can follow the game.
- under 60 mm Tight You watch over a shoulder. You will stand up when play comes to your end.
Where the numbers do not add up
Two tensions in the published figures. Neither is smoothed over here — they stand as they are, because a guide that hides its own cracks is worth less than one that points at them.
- Sector А falls out as the remainder: 2,741 for domestic matches and 2,841 for UEFA. That makes sector А 100 seats LARGER under UEFA, while every other sector shrinks. The figure stands as computed, unsmoothed — most likely it comes from the boxes being counted differently.
- Sector А has 105 seats per row against 182 in sector В, though the two stands are the same length. The difference is the space taken by the boxes, the restaurant and the premium zones.
How wrong we might be
Very. The seat counts are now announced, but the numbers that actually drive the sightlines are not: for all 4 sectors the distance to the first row, the rise per row and the row depth are still marked estimated — plausible for a UEFA category 4 bowl of roughly 18 540 seats, but not measured here.
An error of two or three centimetres in the rise per row moves the C-value by some thirty millimetres — enough to cross a whole band. That is why we show the inputs as well as the result: you can see where the answer comes from, and where not to trust it.
What the model deliberately leaves out:
- the staggering of seats between rows, which in practice improves the view;
- differences in people’s height;
- railings, posts and the angles of the roof;
- the fact that everyone stands up for a goal.
When real measurements arrive for a sector, it gets marked as measured and the warning drops away. Until then it stays everywhere a number is shown — not tucked away here.
Corrections and takedowns
If something is wrong — write. We fix it and note when. If you hold rights to something here and think it should not be up, write to the same address; it comes down without an argument.
A recommendation, an idea or advice on how to make the site better — the same address. It is a letter, not a mailing list.
Money
The site makes no money and does not try to. There are no ads and there will not be. The only place anything is asked for is one support link at the bottom — and nothing depends on it.
