LaTex: Get figure caption to align with image

Question

Thanks in advance for your help!

I know similar questions have been asked, but I cant get any of them to work. I am trying to get the caption to be the same width as the image I am captioning.

Here is the code: it results in all of the words falling in line after the Figure title (image attached to show what it currently looks like. 1

\documentclass[twoside,twocolumn]{article}

\usepackage{blindtext} % Package to generate dummy text throughout this template 

\usepackage[sc]{mathpazo} % Use the Palatino font
\usepackage[T1]{fontenc} % Use 8-bit encoding that has 256 glyphs
\linespread{1.05} % Line spacing - Palatino needs more space between lines
\usepackage{microtype} % Slightly tweak font spacing for aesthetics

\usepackage[english]{babel} % Language hyphenation and typographical rules

\usepackage[hmarginratio=1:1,top=32mm,columnsep=20pt]{geometry} % Document margins

\usepackage{lettrine} % The lettrine is the first enlarged letter at the beginning of the text

\usepackage{enumitem} % Customized lists

Answer 1

• Very important: never ignore error messages. If an error tells you that you mustn't use floatrow with the float package, don't ignore this error and remove one of the packages.

• Then if you don't want the caption to have an hanging indent, remove the hang option from the caption package.

• don't abuse the letter x as multiplication symbol. Use \times instead.

• have a look at the siunitx package to get correct spacing and fonts for units

• with 7.5cm your image is too wide for your column, a warning in the log file will tell you this. You can avoid this by using \linewidth .
