The Big and Small Contest is open to Instructables that make versions of objects that are either larger or smaller than their real-life counterparts.

So no average-sized projects in this contest, or anything that's at 1:1 scale. To be eligible for this contest, your projects must be REALLY HUGE or itty-bitty tiny!

To make things even more interesting, we are offering a Telescope Judges Prize for the author that thinks the largest, and a Microscope Judges Prize for the author who is focused on the tiniest details.

The Big and Small Contest is closed.

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between Nov 12, 2018 and Jan 7, 2019 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Big and Small Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


Instructables members can vote for an entry during the contest plus 3 days after the contest closes.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be announced here on the contest page. All entrants will be notified when this happens.
