Hi Sashi,<br>
<br>
First when I read your mail I thought - ok, this guy did not print
out the PDF on a 100% scale. Forgive me, but I lot of people ignore
this option and then complain.<br>
<br>
But your case seems to be a bit more complex.<br>
<br>
What I propose is that you do not use EPSG 4326. Keep using your
meter based projection and use a different CRS (e.g. EPSG 4326) just
for your map grid. Since 2.6 (I believe), it is possible to define
the CRS for the map grid separately and even have multiple grids on
the same map. Please use this approach and see if it works better.<br>
<br>
Getting a correct map scale for CRS 4326 (Plate Caree projection) is
hard - since at every latitude the scale is different.<br>
<br>
Hope this helps,<br>
Andreas<br>

<div dir="ltr">Dear All,
<div>This is my first post to the forum as a new member. I
seemed to be jinxed by a scale distortion problem. I am using
windows 8.1 version, Qgis 2.8.1, installed as standalone
version. </div>

<div>Here is my problem, I am setting the scale in the Map
composer as 1:250,000 for a test print of A4 size sheet. i
know the straight line distance of two points in the vector
layers of map view. The distance is 52.5 km approximately. For
the above scale it means 1cm = 2500 m (2.5 km). For the
distance between the known points it should measure as 21 cm
in a printout. I exported the map composer sheet to pdf file
and then printed it. Now when i measure the distance between
the known points, it measures only 17.8 cm instead of 21 cm or
the distance on ground is calculated as only <br clear="all">
<div>44.5 km. So for the printed map, the scale is not
1:250,000 as fixed in the map composer, but 1:295000</div>
<div><br>
</div>
<div>While printing i have taken care that, auto scaling / fit
to page etc from printer setting is disabled. So i guess i
print as it came out of the map composer.</div>
<div><br>
</div>
<div>My question in simple terms: does the map composer scale
and printed map scale match in a normal course? What is the
mistake i am doing. Am i ignoring the projection effects or
any other basic criteria in creating the map composition?
How do i make sure that the scale in the printout is same as
the map composer scale?</div>

<div>Thanks for your help</div>

</div>
<div>ps: All my layers CRS is EPSG 24343 (Kalainpur 1975 / UTM
zone 43 N), I am using EPSG 4326 OTF to get lat long to be
printed on the map. The distance between points is measured
horizontally across the map.</div>
