With any other paper-based tests, it's always best to check before the day of the test to make sure you don't fall foul of a similar ban. Whether this is actually true or not (either now or in the past) is irrelevant: the ban stands, and so it's best not to put your score at risk. This is largely because the machines that automatically read these tests are believed to have difficulty picking up the marks made by mechanical pencils. In particular, you must not use a mechanical pencil on the ACT or SAT tests in the United States. While mechanical pencils have numerous good qualities, the one disadvantage is that they are often banned for standardised tests. Why are mechanical pencils banned on SATs? Finally, ‘F’ and ‘HB’ leads lie in the middle. Hardness is represented by a number followed by ‘H’ the higher the number, the harder the lead. A soft lead will be darker and more prone to smudging, while a hard lead is better for leaving light, fine lines. Softness is represented by a number followed by ‘B’ the higher the number, the softer the lead. It's not just about size, though: also consider the hardness of the lead. Other sizes are also available for specialist uses. A thicker, 0.7mm lead, meanwhile, may be better for sketching and non-detailed drawing. For writing and most drawing, you’ll probably prefer a 0.5mm lead. If you wish to draw very fine lines, you’ll want to go for a 0.3mm lead. Mechanical pencils are also favoured by anyone wishing to produce neat and elegant handwriting. Many artists also prefer mechanical pencils, even for more expressive and imaginative work, because the size and weight of the lead remains consistent, whereas a wood pencil gets finer the more you sharpen it. Mechanical pencils are commonly used by professionals involved in technical drafting, such as engineers and architects. So if you take the initial cost of a mechanical pencil, and divide that by the number of wooden pencils you'd probably go through over a similar time period, it starts to look like very good value indeed. As long as you're happy to keep refilling the lead in a mechanical pencil, which doesn't cost very much at all, then it should last for years. Mechanical pencils are generally more expensive than wooden ones, but bear in mind that the latter won't last very long. Why are mechanical pencils more expensive? The fine lines also tend to be easier to erase. And of course, you don't have to carry a sharpener with you all the time. More importantly, it means mechanical pencils provide more consistent lines, enabling you to create more precise and accurate drawings, and neater handwriting. ![]() The main benefit of mechanical pencils is they don't need sharpening. This saves you a lot of hassle and mess. Why are mechanical pencils better than wooden pencils? When the lead has been fully used, you then simply insert a new replacement. A mechanical pencil, in contrast, uses an internal spring to push the lead upwards into the barrel, when you press the button at the other end. ![]() With a normal pencil, once the graphite tip (commonly referred to as 'lead') has blunted, you need to sharpen it using a pencil sharpener. The best mechanical pencils: questions How do mechanical pencils work? Our guides are regularly updated to ensure our recommendations are current. We also trawl reputable sites for user reviews and use these to inform our recommendations. In order to select products for our buying guides we either test them ourselves, or rely on recommendations from our extensive creative network. For light, detailed marks, meanwhile, you might want to go in the opposite direction, and try an ultra-fine 0.3mm lead.Ĭreative Bloq is a team of art and design enthusiasts who are familiar with what it means to be a creative in today's climate. ![]() For most types of drawing, a 0.5mm lead is best, but a thick 0.7mm lead can be better for shading, sketching and non-detailed work. The best mechanical pencils for drawing, also called automatic or propelling pencils, allow you to create everything from quick sketches to technical drafting with clean, precise lines. Meanwhile, to further build up your artist toolkit, don't miss our guides to the best pencils of all kinds, the best pens for artists, and for expressive work and special effects, the best watercolour pencils. We'll start with the best pencils for drawing, but if you're only interested in writing then skip ahead to the best mechanical pencils for writing. In this article, we've gathered together the best mechanical pencils on the market today, selected from a mixture of recommendations from artists as well as extensive internet research. And because replacement leads are cheap it saves you money over time, because you won't have to buy new pencils. Crucially, the pencil itself stays the same length, unlike wooden pencils which get shorter as you sharpen them (even with one of the best pencil sharpeners).
