After independently releasing three albums herself between 2009 and 2010, Meghan Trainor decided to write songs for other singers because she considered herself "one of the chubby girls who would never be an artist".{{cite news|author=Sullivan, Jim|url=http://www.capecodtimes.com/article/20140830/ENTERTAIN/140829518|title=Meghan Trainor Hits Big Time with 'All About That Bass'|work=Cape Cod Times|date=August 30, 2014|access-date=June 2, 2015|archive-url=https://web.archive.org/web/20150529082618/http://www.capecodtimes.com/article/20140830/ENTERTAIN/140829518|archive-date=May 29, 2015|url-status=live}} In 2012, she signed a publishing deal with Big Yellow Dog Music, a Nashville, Tennessee-based music publishing firm, and moved to Nashville the following November.{{cite magazine|author=Hampp, Andrew|url=http://www.billboard.com/articles/news/6259143/meghan-trainor-interview-all-about-that-bass-embracing-body|title=Meghan Trainor: 'I Don't Consider Myself a Feminist'|magazine=Billboard|date=September 22, 2014|access-date=December 30, 2014|archive-url=https://web.archive.org/web/20150609064955/http://www.billboard.com/articles/news/6259143/meghan-trainor-interview-all-about-that-bass-embracing-body|archive-date=June 9, 2015|url-status=live}} American songwriter Kevin Kadish met Trainor in June 2013 at the request of Carla Wallace, a co-owner of Big Yellow Dog.

Kadish read a list of potential song titles to Trainor, of which "All Bass, No Treble" was her favorite.{{cite magazine|last=Edwards|first=Gavin|url=https://www.rollingstone.com/music/music-news/how-meghan-trainor-became-2014s-most-unlikely-pop-star-182692|title=Meghan Trainor on How She Became 2014's Most Unlikely Pop Star|magazine=Rolling Stone|date=October 27, 2014|access-date=January 3, 2015|archive-url=https://web.archive.org/web/20180830210206/https://www.rollingstone.com/music/music-news/how-meghan-trainor-became-2014s-most-unlikely-pop-star-182692/|archive-date=August 30, 2018|url-status=live|url-access=limited}} Trainor was inspired by her teenage problems with self-acceptance and body image, and suggested these as a basis for the lyrics. She told Rolling Stone Kadish had experienced similar problems during his childhood and could relate to these themes. She suggested a booty theme with "it's about the bass, not the treble".{{cite magazine|author=Hampp, Andrew|url=https://www.billboard.com/music/music-news/meghan-trainor-all-about-that-bass-number-one-charts-2014-billboard-cover-6405533/|title=Meghan Trainor on 'All About That Bass' Number One|magazine=Billboard|date=December 12, 2014|access-date=December 29, 2014}} Trainor was also inspired by Bruno Mars's "Just the Way You Are" (2010), and criticized the use of electronically edited images in beauty magazines.{{cite news|author=Sullivan, Caroline|url=https://www.theguardian.com/music/musicblog/2014/sep/01/pops-weighty-issue-all-about-that-bass-body-positive-anthems|title=Pop's Weighty Issue: 'All About That Bass' and Other Body-positive Anthems|work=The Guardian|date=September 1, 2014|access-date=January 5, 2015|archive-url=https://web.archive.org/web/20141213192331/http://www.theguardian.com/music/musicblog/2014/sep/01/pops-weighty-issue-all-about-that-bass-body-positive-anthems|archive-date=December 13, 2014|url-status=live}} Kadish played a drum beat while Trainor sang the hook, "I'm all about that bass, 'bout the bass, no treble".

Although both were satisfied with the song, they doubted its commercial prospects. They pitched it to several record labels, who said it would not be successful because of its retro-styled composition and wanted to rerecord it using synthesizers, which Kadish and Trainor refused.{{cite magazine|url=http://www.billboard.com/articles/columns/pop-shop/6214302/meghan-trainor-on-all-about-that-bass-i-wish-there-was-a-song-like|title=Meghan Trainor On 'All About That Bass': 'I Wish There Was a Song Like This When I Was 13'|magazine=Billboard|publisher=Associated Press|date=August 11, 2014|access-date=December 30, 2014|archive-url=https://web.archive.org/web/20141219220644/http://www.billboard.com/articles/columns/pop-shop/6214302/meghan-trainor-on-all-about-that-bass-i-wish-there-was-a-song-like|archive-date=December 19, 2014|url-status=live}} Trainor sang "All About That Bass" for Paul Pontius, who was the A&R manager for Epic Records chairman L.A. Reid. She performed the song the following week using a ukulele for Reid, who signed her with the record label 20 minutes later. Reid decided that the demo, with additional mastering, should be the song's final cut. Speaking in 2015, he said he considered it "lightning in a bottle" and realized at their first meeting Trainor "was going to explode".{{cite magazine |last=Halperin |first=Shirley |title=Top Executive: Epic Records' L.A.

Trainor relates the form of music (bass and treble) to the human body being thick or thin, and asserts the importance of the former. Kevin O'Keeffe of The Atlantic compared its lyrical message to those of Kesha's "We R Who We R" (2010), Pink's "Fuckin' Perfect" (2010), and Sara Bareilles' "Brave" (2013), among others.

As "All About That Bass" began rising in popularity, Radio Disney's vice president of programming Phil Guerini asked Epic to send it a family-friendly version of the song with lyrics suitable for all audiences. The record label agreed to this because it wanted to maximize airplay and reach as many radio formats as possible.{{cite magazine|author=Trust, Gary|url=http://www.billboard.com/articles/columns/chart-beat/6266667/ac-radio-disney-are-all-about-that-edited-bass|title=AC, Radio Disney Are All About That (Edited) 'Bass'|magazine=Billboard|date=September 30, 2014|access-date=December 29, 2014|archive-url=https://web.archive.org/web/20141227145710/http://www.billboard.com/articles/columns/chart-beat/6266667/ac-radio-disney-are-all-about-that-edited-bass|archive-date=December 27, 2014|url-status=live}} In the bowdlerized version, the line "But I can shake it, shake it, like I'm supposed to do" was replaced with "But Imma make it, make it, like I'm supposed to do"; and the line "Boys like a little more booty to hold at night" became "Boys like the girls for the beauty they hold inside"; it was also used on adult contemporary radio stations. Trainor and Kadish refused to make this version available for digital download because they believed it would "water down" the original.

Two girls are shown playing with dolls in a dollhouse, dancing in a bedroom, and riding bicycles.
