# A topo is a route drawn by somebody who did it

> The dashed line up a crag isn't a map — it's a first ascentionist's account of where the holds are, and the grade in the box is an argument that has been running for decades.

A face drawn in outline, a dashed line running up it, pitches numbered, and a small box in the
corner containing a grade.

That drawing is somebody's memory of climbing it, written down so other people could find the same
holds.

## Why is a topo the right artefact?

Because it's a first-person account pretending to be a map.

A real map is surveyed. A topo is drawn from below, by hand, by the person who put the route up,
based on what they remember about where the line goes. It's subjective, sometimes wrong, and
argued about — which is precisely why climbers care about them.

That's a document with a *voice*, which is rare in technical drawing and part of why the format
reads warmly.

## What's the grade box doing?

Starting a fight.

A grade is the most contested number in the sport. It's a consensus estimate, it drifts by region
and decade, and everybody who repeats a route has an opinion about whether it's soft or stiff.

Putting one on a shirt is therefore doing something a symbol can't: making a claim that other
climbers will immediately evaluate.
[The number is legible to everyone and meaningful to almost nobody](/stories/numbers-as-a-design),
except the few hundred people who've been on it.

## What should the route be?

One you climbed, or one you failed on.

The famous routes are everybody's and they read as a list of places visited. The interesting shirt
is a line at a local crag nobody outside a county has heard of — because that's the version whose
audience is real and small.

The failure version is better still. A topo of the route that shut you down, with the high point
marked, is a joke and a record at once.

## Can I use a guidebook's topo?

No — guidebook topos are the authors' and illustrators' work, and climbing guides are a small
publishing world that depends on those sales.

The convention is free: hand-drawn faces, dashed lines, numbered pitches and grade boxes are a
documentation format, not a design anyone owns.

Drawing your own is also more accurate to the tradition, which began with people sketching lines
on the back of an envelope for a friend.

## What else belongs on it?

The furniture of the format, and not much else.

- **Numbered pitches** with a small circle at each belay.
- **A dashed line** for the route, solid for the ground.
- **Height marks** or a metre figure at the top.
- **A grade box**, small, in a corner.
- **A route name**, hand-lettered.

Route names are their own pleasure — the tradition allows anything, and the good ones are dry,
local and slightly rude.

## Does it work for indoor climbing?

Differently, and the equivalent document is the tick list.

Indoor climbing's artefact isn't a topo, it's a scorecard: problem numbers, colours, a grid of
attempts. That's a real and unmined format with the same properties — meaningless outside a
specific wall, complete to anybody who's been there.

Same principle as everywhere in this batch:
[find the document, not the symbol](/stories/nurse-shift-shirt).

## Does it print well?

Yes — it's line art with strong structure.

The face outline and the dashed route are hard-edged and hold at any size. The one thing to watch
is hatching for rock texture, which fills in on fabric if it's drawn at guidebook density —
[coarser than the original](/stories/bold-shapes-survive-fabric).

One or two inks on a mid-dark ground. It reads as a page torn out of something, which is correct.

## How do I get one made?

Describe the route at [JustOG](/) — the crag, the line, the pitches and the grade you'd argue for.
Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to
order and shipped.

Designs other people have published are in the [shop](/shop).

Somebody stood at the bottom and drew that from memory so you could find it.
