Density, ATS-safe construction and tooling

The previous lesson covered how to judge a template. This one covers how to build and keep one: how much a page can hold, the construction rules that keep it parseable, and the tool you build it in.

All three come back to the template's third job, staying editable. A page with no room to spare, a layout that breaks when you move a bullet, or a tool that makes every change painful will each stop you tailoring, and tailoring is worth more than any design choice.

Whitespace and the density budget

The instinct when a resume overflows is to squeeze. This makes the document worse in a way that is hard to see when you are the one who wrote it.

A crammed page reads as unedited, and the reader feels the density long before they read a word.

What whitespace is doing

Space between sections is not wasted. It is the signal that a section has ended, and it is how a skimming eye finds entry points into the page.

Remove it and the page becomes uniform. A uniform page has no anchor points, so the fast reader gets nothing at all and moves on.

The density budget

At readable settings — 10–11 pt, 1.1 line spacing, 1.5–2 cm margins — one page holds approximately:

Element	Rough capacity
Contact block	2–3 lines
Summary (if used)	2–3 lines
Experience entries	3–4 roles
Bullets total	10–14 across all roles
Skills	3–4 lines
Education	1–2 lines

Treat this as a budget. If you want an eleventh bullet, something else has to leave.

When you are over

Do these in order. Stop as soon as you fit.

Cut the weakest bullets. Almost always sufficient, and it improves the page (see Signal versus noise).
Tighten wording. Most bullets shrink 15–20% with no loss of meaning.
Compress old roles. Anything more than about eight years back can become one line.
Reduce margins slightly — to 1.5 cm, not below.
Reduce font size — to 10 pt, not below.

Steps 4 and 5 are last for a reason. They make the page harder to read while creating the impression that you have solved the problem.

Deliberate emptiness

A slightly sparse resume from a candidate with two years of experience is correct, not a deficiency. Filling that space with weak material lowers the average quality of the page.

Empty space is better than a bullet that says Participated in daily standups.

Building for ATS safety

The parsing rules have come up across several sections. Here they are consolidated into one buildable checklist.

ATS safety is a construction rule plus a ten-second check, not a set of superstitions about keywords.

The safe construction

Structure

Single column for all main content.
Standard section headings: Experience, Education, Skills, Projects, Summary.
Linear reading order top to bottom.

Content placement

Nothing important in headers or footers — many parsers skip those regions entirely.
No text inside images or icons.
No text boxes.
No tables. Use tab stops or right-alignment for dates.

Text

Real, selectable text throughout. Never a scan or an exported image.
Standard fonts.
Simple bullet characters — a plain round bullet or a hyphen.
Consistent, unambiguous dates: Mar 2024 – Jun 2025.

File

PDF, unless told otherwise.
Sensible filename.
Text-based, not image-based.

The verification

What you are not required to do

To be clear, since the opposite is widely claimed:

You do not need to remove all formatting. Bold, italic, and bullets are all fine.
You do not need a specific font.
You do not need to match a keyword percentage.
You do not need a plain-text version.

The requirement is parseability, not blandness. A well-designed single-column resume with clear hierarchy parses perfectly and looks good.

Tooling

Last, the tool you build it in. There are four ways to build a resume, with honest trade-offs.

The tool is irrelevant to the reader — pick whichever one you will actually keep updating.

The options

Tool	Control	Portability	Parse quality	Best for
Google Docs	Medium	Excellent	Good	Most people
Microsoft Word	Medium	Good	Good	Those already using it
LaTeX	Excellent	Poor	Good (if built well)	People who already know LaTeX
Resume builders	Low	Poor	Variable	Getting something acceptable quickly

Google Docs

The default recommendation for most people. Free, accessible anywhere, easy to duplicate for variants, exports clean PDFs, and simple enough that tailoring stays quick.

Its limitation is fine typographic control, which most resumes do not need.

Microsoft Word

Equivalent in practice, with better typographic control. Use it if it is already your tool.

One caution: if you send the .docx rather than a PDF, your layout depends on the reader's fonts and version. Export to PDF unless asked for the editable file.

LaTeX

Produces excellent typography, and there are well-known templates. Genuinely the best output if you already know it.

Two honest cautions:

Editing friction. Tailoring means recompiling. If that friction stops you tailoring, you have traded a large benefit for a small one.
Some templates parse badly, particularly the two-column ones with sidebars. Run the copy-paste check.

If you do not already use LaTeX, learning it for this is not a good use of your time.

Resume builders

Web tools that generate a resume from a form. They will get you to something acceptable quickly, which has real value if you are stuck.

Watch for three things: they favour two-column designs, they often include skill rating bars, and some restrict export or add branding behind a paywall. Check the output against the checklist in Building for ATS safety before trusting it.
