Choosing a CV layout: sidebar or single column?

Layout does not get anyone hired, but the wrong one can get in the way. The right choice depends less on taste than on three practical questions: how the CV will be read, how much you have to fit in, and what your field expects.

The two basic shapes

Almost every CV is one of two shapes.

A two-column CV has a narrow sidebar for short facts - contact details, skills, languages, certifications - and a wide column for your work history. A single-column CV puts everything in one full-width column, read from top to bottom.

Question 1: who, or what, reads it first?

This matters more than anything else.

If you are uploading it to an application portal - the kind where you create a login and the site tries to fill in a form from your CV - software reads it before a person does. Many of these systems now handle two columns properly, but not all, and you cannot tell from the outside which one an employer uses. A parser that reads straight across the page will interleave your sidebar with your work history. A single column removes the risk entirely. In CV Editor that means Single Column or Single Serif. The ATS guide explains what these systems do and how to test your own file.

If you are emailing it to a named person, handing it over, or sending it through a recruiter you have spoken to, a human reads it first, and layout is about making their thirty seconds productive. A sidebar helps: they can find your phone number and your main skills without reading a sentence.

If you do not know, or you are sending the same CV to many places, use a single column. It is never the wrong answer; it is only sometimes the less compact one.

Question 2: how much do you need to fit?

Count your short items - skills, tools, languages, licences, certifications, interests. If you have fifteen or twenty of them, a single-column layout spends a lot of page on a list, and a sidebar absorbs them neatly beside your experience. If you have only a handful, a sidebar will look empty, and a single column is the better fit.

Then look at length. A sidebar cannot continue on to a second page in a way that makes sense, so everything in it has to fit the height of one sheet. If the editor shows Sidebar overflows, you have three options: trim the sidebar, shrink the photo or body text slightly, or accept that a single column suits this CV better.

If you are a line or two over a page, try a tighter design before you start cutting content. Slate uses the same structure as the default with closer line spacing and holds noticeably more.

Question 3: what does your field expect?

Conventions vary, and a CV that looks out of place makes the reader work harder.

• Law, finance, government, academia, medicine. Conservative. A serif typeface, black text, minimal colour. Academic and medical CVs are long by nature, so single column is the norm.
• Commercial, operations, sales, administration, healthcare support. A clean sidebar layout in a restrained colour is standard and reads as organised.
• Marketing, design-adjacent and client-facing roles. More visual confidence is welcome. A filled band of colour is acceptable here in a way it would not be for a judge's associate.
• Software, data and engineering. Content over decoration. Either shape works; many technical hiring managers prefer plain. A monospaced heading font is a well-understood nod to the trade.
• Trades, logistics, hospitality, retail. Clarity above all: licences, tickets and availability easy to find. A sidebar is useful for exactly that list.

Country matters too. A photo is routine in parts of Europe and Asia and unusual in Australia, the UK, the US and Canada, where a one-column CV without one is the safest form. See CV or resume? for the regional differences.

Left sidebar or right?

People start reading at the top left. A left sidebar means the first things seen are your photo, name and contact details, followed by the work history. A right sidebar means the first thing seen is your most recent role, with the sidebar acting as a reference panel. If your experience is your strongest card, Right Rail leads with it. A right-hand sidebar is also kinder to software that reads left to right, because your experience comes out before your skills list rather than tangled into it.

Serif or sans-serif?

Both are perfectly readable at CV sizes. The difference is tone. A sans-serif such as Helvetica looks modern and neutral, and is the default almost everywhere. A serif such as Times looks traditional and formal, and is slightly more economical with space. Choose the one that matches the field, and do not mix more than two typefaces on one page.

Whatever you choose, keep body text at a size people can read without effort. Sidebar layouts can go a little smaller because their lines are short; full-width lines need larger type to stay comfortable. If you find yourself shrinking text to make things fit, cut words instead.

Colour

One accent colour, used for headings and nothing else, is enough. Keep it dark enough to read when printed in black and white: export the PDF, print a page in greyscale, and check that headings are still clearly darker than the paper. Filled bands of colour look striking on screen but use a lot of ink and can print as a heavy grey slab, so they suit CVs that will be read on a screen.

A quick way to decide

You do not have to choose only once

Because the layout is separate from the content, there is no cost to keeping two versions: a single-column one for portals, and a sidebar one to email or hand over. Switching design in the editor never changes your text. Export one, switch, export the other, and name the files so you know which is which.

Before you send either, do the thirty-second test from the ATS guide: open the exported PDF, select all, copy, and paste into a plain text editor. If what you see reads in a sensible order, software will cope with it. If your skills list turns up in the middle of a job description, switch to a single column for that application.
