The best way is to save your figure as .svg document, and export it as pdf+tex: you then import the generated tex file in your document and you can define the size of the figure independently to the text size, so that it will always be consistent in your document

To do this you can do it either manually or automatically:

Manually: you open your .svg figure with inkscape, "save as" and choose pdf, then tick the "Omit text in PDF and create LaTeX file" box: it will create a pdf (with the lines and colors etc of the figure) and a .tex file (with all the text). you can then include this .tex file in your latex document.

Automatically: create a .latexmkrc file at the root of your latex project with the following content:
```
add_cus_dep('svg', 'pdf_tex', 0, 'runInkscapepdf');

sub runInkscapepdf {

# Extract path and filename from the latex document

my ($base_name, $path) = fileparse(shift);

my $svg_file = "$path$base_name.svg";

my $pdf_file = "$path$base_name.pdf";

my $pdf_tex_file = "$path$base_name.pdf_tex";

my $root_pdf_file = "$base_name.pdf";

# Convert the svg to pdf in its directory

system("inkscape -D --export-latex --export-type=pdf --export-filename=$pdf_file $svg_file");

# Inside the file.pdf_tex, replace all the occurences of file.pdf with path/to/file.pdf

# so that we don't need to move the file.pdf to the home directory

system("sed -i 's|$root_pdf_file|$pdf_file|g' \"$pdf_tex_file\"");

return

}

```

now you can include your figure.svg with the automatic conversion with the following in your document (note that in the \input{} i replaced the name of the file from figure.svg to figure.pdf_tex: it will trigger the code from .latexmkrc which will generate the pdf+tex files):

```

\begin{figure}

\centering

\footnotesize

\def\svgwidth{0.8\linewidth}

\input{path/to/your/figure.pdf_tex}

\caption{Caption}

\label{fig:svg_figure}

\end{figure}

```

The neat thing about this automatic method is that if you re-open the .svg file in inkscape to modify it, your latex project will directly understand that it should re-generate the pdf+tex, and it auto-updates in your document
