<p>I'm not sure exactly what you mean by your comment to Davo's answer, but with respect to your use of a sheet of paper reference, it seems like you can still use <em>80 gsm</em> paper as a reference for 0.1&nbsp;mm layers.</p>

<p>From <a href="http://www.printware.co.uk/Blog/311/Paper-Sizes-Explained.html" rel="nofollow noreferrer">Paper Sizes Explained</a> (emphasis is mine):</p>

<blockquote>
  <p>There is no universal calculation for the thickness of paper based on the gsm as varitaions in paper composition can affect the weight, so two different brands of 120gsm paper could have slightly different thicknesses. However, <strong>an average sheet of 80gsm paper, the most commonly used weight, measures approximately 0.1mm in thickness</strong>, which means that <em>10 sheets would measure 1mm</em>. By comparison, <em>10 sheets of 120gsm paper would be 1.5mm thick</em>, assuming the paper composition was the same.</p>
</blockquote>

<p>So, given that:</p>

<ul>
<li>80&nbsp;gsm => 0.1&nbsp;mm</li>
<li>120&nbsp;gsm => 0.15&nbsp;mm</li>
</ul>

<p>Then </p>

<ul>
<li>40&nbsp;gsm => 0.05&nbsp;mm</li>
<li>60&nbsp;gsm => 0.075&nbsp;mm</li>
</ul>

<p>From <a href="http://www.officexpress.co.uk/paper-guide/" rel="nofollow noreferrer">A Guide to Paper Types and Sizes</a></p>

<pre><code>Paper Weight Descriptions

Weight        Feels Similar to:

35-55 gsm     Most newspapers
90 gsm        Mid-market magazine inner pages
130-250 gsm   A good quality promotional poster
180-250 gsm   Mid-market magazine cover
350 gsm       Most reasonable quality business cards
</code></pre>

<p>So, it would appear that you could use a newspaper sheet (or two) to test for layers of less than 0.1&nbsp;mm.  Obviously this would depend upon where in the world you are, and the (physical) quality of your newspapers. Here in the UK, or rather Europe, the <em>exported version</em> of the Guardian used to be printed on some extremely lightweight paper (almost transparent tissue thin), in order to keep the costs of transport down to a minimum. So a folded sheet of that would certainly be in the range of 0.75 - 0.99&nbsp;mm (which seems to be the range that you are looking for). However, given that the printed media (as opposed to the online version) is currently in decline, I am not entirely sure if it is still available.</p>

<p>Or, how about grease proof paper? From the <a href="https://en.wikipedia.org/wiki/Greaseproof_paper" rel="nofollow noreferrer">Wikipedia entry</a>:</p>

<blockquote>
  <p>Basis weights are usually 30–50 g/m²</p>
</blockquote>

<p>Although, this paper has been processed (<a href="https://en.wikipedia.org/wiki/Supercalendered" rel="nofollow noreferrer">supercalandered</a>) and treated with starch, which will increase the density, so the thickness will not correlate to the table above (i.e. it will be thinner).</p>

<p>Giftwrap paper (not the really thick stuff) could be another option.</p>

<p>After having doing some long winded googling, I guess that the best bet would be to get hold of a micrometer and measure whatever paper yourself, as the specifications of paper are generally given in <code>gsm</code> and not <code>mm</code> (which is a bit annoying), and so it is somewhat difficult to provide you with a definitive answer (without physically measuring it).</p>

Paper (once folded) or glossy thick paper (~130-150 g/m²) are common uses for calibrating the printer,

@Trish - Yeah, but I think that the OP wants something thinner than that... I am not quite sure, the question is a little unclear, but seems to want a household object less than 0.1 mm and not for calibration *exactly* but more like a squashed first layer. TBH, I don't really understand :-)

<p>Maybe a better way to visualise 0.1mm is to explain that it only becomes really visible on a shallow slope. A 10 degree slope will place one layer boundary every 8mm, and these steps will probably be visible on a print.</p>

<p>For a sphere, such as the 3D-hubs marvin, this means that the top portion will have a clear layering, but the majority of the shape should have minimal visible layers. For example, this was printed at 0.1mm layer as a test:

You could also say that the layer is about the same as the embossing on a typical coin (using the same photo as a reference), but realise that the resolution of embossing is greater.</p>

<p>Looking inside the eyes of this model demonstrates how a gentle slope exposes the presence of layers.</p>

That kind of misses the point. I have a set of spark plug gappers I could use, too, but this is more about understanding at a deeper level and communicating with others, especially those unfamiliar with 3d printing.

I didn't glean that from your original post. You stated that **you** wanted to get an approximation of how thick 0.1mm is. What information are you actually looking for? A sheet of printer paper is the best approximation from normal household items.

<p>I have a printer with a 0.1 mm typical layer thickness. Of course I can choose some different sizes in Cura or other slicing software, but most prints on this machine will be 0.1 mm. In my (admittedly limited) experience thus far, the 0.1 mm seems typical for other printers, too.</p>

0.1mm is approximately equal to the distance traveled by light in a vacuum during 1/326th of the period of a transition between the two hyperfine levels of the cesium-133 atom.

What do you mean with "first layer pushes into the bed"? When printing on glass or aluminium that is definitely not happening. Sheet of A4 or letter paper works fine!

0.1mm is 10x the size of a typical yeast cell diameter. It is 50 to 100 times the size of E. coli. It is a 1/100 of a cm. I think this is a particular bad question which is also unrelated to 3D printing. Moreover, I think 0.1 mm is really not that hard to visualize.

"Regular" printer/xero paper is 0.05mm thick. So, this folded in two. Also the most common layer height is 0.2mm (and 0.4mm nozzle), 0.1mm is used for "fine" prints like small figurines or micro-mechanical parts.

I'm not sure exactly what you mean by your comment to Davo's answer, but with respect to your use of a sheet of paper reference, it seems like you can still use 80 gsm paper as a reference for 0.1 mm layers.
From Paper Sizes Explained (emphasis is mine):

By comparison, 10 sheets of 120gsm paper would be 1.5mm thick, assuming the paper composition was the same.

So, given that:

80 gsm => 0.1 mm
120 gsm => 0.15 mm

Then 

40 gsm => 0.05 mm
60 gsm => 0.075 mm
