Understanding the concept of architectural scales and calibration drawings
Calibration drawings allow us to accurately represent sites, spaces, buildings and details to a smaller or more practical size than the original.
When a drawing is described as 'to scale', it ways that each element in that drawing is in the same proportion, related to the real or proposed thing – information technology is smaller or indeed larger by a detail percentage.
If something is 'drawn to scale' we expect that it has been drawn, or printed, to a common scale that is used equally standard in the structure industry. As we gain a amend agreement of scale, we tin can view a cartoon in a particular scale and instantly recognise and understand the spaces, zones and proceeds a quick understanding of the existing or proposed spatial relationships.
In the real world, i meter is equal to 1 meter. A cartoon at a calibration of one:10 means that the object is 10 times smaller than in real life scale 1:1. You could as well say, i unit in the drawing is equal to 10 units in real life.
As the numbers in the scale get bigger, i.e. 1:50 – 1:200, the elements in the drawing actually get smaller. This is considering in a drawing at 1:50 in that location is 1 unit for every l unit in real life. A drawing of 1:200 is representing 200 units for every one unit of measurement – and therefore is showing the elements smaller than the i:50 drawing.
It is worth noting that scale drawings stand for the same units. So, if a drawing is at one:50 in cm, 1cm in the drawing volition be equal to 50cm in existent life. Similarly, if a drawing is in mm, at 1:200 – one mm unit in the drawing will represent 200mm in existent life.
The prototype above shows an example of a cartoon set with unlike scales to demonstrate different aspects of the design. (cad drawing courtesy of bibliocad.com). You may want to represent a site plan at a scale of one:500, but perhaps prove floor plans at 1:100 for example.
Working with scales for architectural representation
In compages, we use a collection of standard scales to stand for our designs. For example, it is common exercise to produce flooring plans at a scale of 1:100 (dependent on size of project and newspaper). Once yous gain an agreement of scales, information technology is easy to sympathize which calibration is most suited to which type of drawing.

These scale confined prove what one unit of measurement represents at different scales.
The full general requirement of a scaled drawing is to convey the relevant information clearly with the required level of particular. If you are working in do in that location will frequently be office standards. For example, they may just employ layout sheets of either A3 or A1 – depending on the calibration of the projection and information that is being represented. As a student, you need to make these decisions based on manufacture standard. It is ever all-time to use a 'circular' scale, i.e., ane of the scales mentioned below, and non make up your ain.
What scale should I use?
The following looks at the recommended scales for architectural use in the metric system. The chosen scale and paper size will often depend on the size of site/pattern of each individual project.
Location Programme and Primal Plans
one:1250 (often requested by planners)
1:1000
1:500
Site Plans, Sketch schemes etc
1:200
1:100
Plan drawings – floor plans, elevations, sections
i:100
one:50
Room plans, interior elevations
1:20
Component / detail drawings
1:x
ane:5
Working out the scale
A scale is shown as a ratio, for instance 1:100. A drawing at a scale of 1:100 means that the object is 100 times smaller than in real life scale 1:1. You could also say, i unit in the drawing is equal to 100 units in existent life.
So, if we were drawing a table that measured 100cm wide by 200cm long at a scale of i:l, yous would draw the table 2cm wide by 4cm long on your slice of newspaper. This is worked out by dividing the real life size (100cm) by 50 (1:fifty scale). This gives you a result of 2cm. For the length of the tabular array we divide 200cm by l to get a consequence of 4cm.
Of grade, it is not necessary to calculate the required measurements when yous depict. You can either apply a calibration ruler to hand draw your plans, or software such as Revit, AutoCAD, ArchiCAD that volition permit you to present your drawings at any scale and easily switch between scales every bit required.
How to use a calibration ruler
A scale ruler is a tool that architects, engineers and designers use to draw their designs at an appropriate calibration that it fits on a piece of paper and is in proportion to accurately convey the scheme. The scale ruler comes in different shapes, flat or triangular but they all provide sets of graduated numbered spaces, that establishes a proportion of one unit of measurement to the specified unit, i.due east. different scales. As an example, the ruler I have in front of me at present has the post-obit scales; one:1, 1:100, ane:20, ane:200, 1:five, 1:500, ane:1250, one:2500.
Scale rules have varying number of scales on them, depending on their intended utilise. Using a calibration rule is pretty easy when you know how.
When yous are drawing a plan, you select the scale y'all intend to use by turn the ruler to the appropriate side. You tin can then draw the line to the desired measurement using the scale ruler. For example, if y'all have select to draw a 5m wall at 1:100, yous would select your 1:100 side of the ruler, and depict v units along the ruler, as each unit represents 1m.
When you are reading plans, yous establish the scale of the drawing or plans, and select that calibration on your ruler, you are and then able to measure the lines using the correct scale.
How to scale a drawing upwards or down
Permit'south await at converting a calibration drawing to a different scale. You can considering irresolute the calibration of a drawing past a decimal factor or by a percentage. For example, lets imagine we have a drawing at 1:50, but nosotros want amend the scale, to show that cartoon at 1:200. A drawing at 1:200 is 4 times larger than a drawing at 1:fifty, therefore nosotros would need to increase the size of the cartoon four x. The table below demonstrates the different scale factors required to convert a scale up or down.
Table: Converting scales up or down
Being able to scale drawings up and down using percentages has become very useful likewise. Working in Adobe (Photoshop, InDesign etc), you will discover you can adjust the size of an object using a percentage, which is great if you are wanting to accurately scale a cartoon upwardly or downward while working in photoshop while maintaining a precise scale.
Lets imagine yous are working on a drawing that y'all have imported into an A4 sized photoshop certificate. The cartoon y'all have imported does not quite fit at its current scale of 1:50, and so y'all volition need to reduce the calibration in order to clasp the image onto the folio, while maintaining an accurate scale. By using the tabular array beneath, nosotros can see that to convert from a calibration of 1:50, downwardly to 1:100 we would need to reduce the cartoon by 50%. To exercise this nosotros would brand certain the dimension ratios of the image are locked, and go on to blazon l% into the size box.
Obviously this is a uncomplicated example merely you lot get the thought. The table below provides the basic conversion percentages to scale a drawing up or down using the standard metric scales.

Newspaper size scales and magnification
We can at present look at alteration newspaper size scales and magnification. At that place are times when you may have a drawing on an A4 piece of paper, that you lot need to calibration up to an A3 piece of newspaper for case. Let's imagine you were needing to trace this drawing so would utilise a photocopier to scale the drawing up to the necessary size.
How to convert paper sizes?
To catechumen the paper size you tin can utilise the percentages in the table beneath. Note that these percentages practice non correspond to the scale factors. And so, if you scale or magnify a paper size accurately, information technology does not mean that you will retain an accurate (or standard) scale of the drawing. So, if you want to increment the scale of a drawing using a photocopier, only want to increase information technology to a standard scale (i:10 for example) then you lot must use the percentage factors for converting scale. If information technology is just the paper size you wish to change, and then yous can use the newspaper size converter. I hope that makes sense.

Working with paper sizes
When working with ISO paper layouts nosotros know that the standard size of paper was developed on the basis of an area of 1m2, divided according to the ratio of the sides.
This bones format of 1m2 then forms the ground for all other smaller sizes. All A sized paper is either halving or doubling the basic format.
X x Y = 1
Below is a list of all the A paper sizes.
Working with scales digitally
One of the neat things well-nigh using digital drafting software is that you can produce drawings every bit multiple scales from one single drawing. Programs such as Revit, AutoCAD, ArchiCAD and many more, permit you to draw up your designs at 1:1 scale, that is real life size, and produce drawings or plots of these designs at an advisable scale for the paper size y'all accept selected.
When working in CAD yous can let the software do some of the hard piece of work for you lot past making use of the paper infinite option to create layouts. On your layout sheet yous are then able to create viewports which feature your drawing at the required scale. I have recorded a couple of tutorials that will assist with setting up drawings for printing at appropriate scales.
I have also recorded a tutorial that explains how to scale a cartoon in cad. This is useful if you lot have imported a drawing at a unlike scale.
